Quality management according to ISO 9001:2015

Quality management according to ISO 9001:2015

ISO 9001:2019 certification

Why do we get certified?

  • The DIN EN ISO 9001:2015 standard is an international standard that demonstrates high levels of quality to customers and third parties.
  • It serves as a catalogue of requirements for a quality management system.
  • The results are optimised internal company processes, minimised rejects, resource conservation, and increased customer and employee satisfaction.
  • An independent certification body confirms compliance with these standards.
  • The aim of the standard is to understand and implement the requirements that interested parties expect the company to meet.

The seven principles of quality management

The ISO 9000 standard explains the seven principles of quality management. They form the basis of quality management and are an important part of applying ISO 9001:2015 appropriately. They are:

  1. Customer focus
  2. Leadership
  3. Engagement of people
  4. Process approach
  5. Continuous improvement
  6. Evidence-based decision-making
  7. Relationship management

Based on this, we apply practices such as risk-based thinking, a process approach and the PDCA cycle throughout our entire quality management system.

The PDCA cycle

The PDCA cycle is a model for sustainably optimising the quality management system in companies. It is a four-step method:

  1. Plan – Determine improvement goals and define necessary measures
  2. Do – Implement measures from the planning phase, document results
  3. Check – Evaluate collected data to make an objective assessment of whether targets have been achieved
  4. Act – Reflect on process and integrate effective improvement measures

This cycle helps to solve problems efficiently and offers several other advantages, such as enabling companies to prevent recurring errors and continuously improve work processes.

Corporate policy of TrueDyne Sensors AG

TrueDyne Sensors AG supports the decision of Endress+Hauser Flowtec AG not to formulate a fully integrated management policy. In our opinion, this enables clearer, more targeted formulations and statements, facilitates understanding for employees and customers, allows for faster and more flexible changes and, from our point of view, offers no disadvantages whatsoever.

Quality = customer satisfaction

We want satisfied and loyal customers

This is why we define quality as customer satisfaction and focus on generating outstanding customer benefits. Through satisfaction, we want to achieve customer loyalty and lasting relationships. All of our planning and actions must be geared to this. Everything we do must also be viewed from the customer’s perspective and must always be based on this key question: “Is what we are doing or planning to do useful and beneficial for our customers, or are we merely concentrating on our company’s growth?” Customer orientation is an essential part of our corporate identity.

We strive for zero defects in products and services

This is an indispensable prerequisite for customer satisfaction and loyalty. Every mistake affects our customers, disrupts their normal processes, and can have serious and perhaps even unforeseeable consequences. Every mistake costs our customers time and money, causes problems, and ultimately dissatisfaction. Over time, dissatisfied customers become disloyal and prefer to obtain their services and products elsewhere. Every customer that we lose weakens our company and strengthens our competitors. It is extremely difficult to win them back. Zero defects can only be achieved if the entire product life cycle is designed and aligned accordingly – from market analysis and product definition to development, production, sales, and shipping. This means that every employee must contribute to the overall effort.

We strive for Operational Excellence

In our company, we apply the LEAN principles to strengthen our focus on operational excellence and thus optimize the quality and flexibility of our products as well as our business processes. As a result, we systematically identify and eliminate activities and processes that do not generate added value through continuous improvement. Our fundamental approach is based on the Kaizen Continuous Improvement Process and we do everything we can to transmit this LEAN culture  to our main suppliers.

We create products and services that we can be proud of

We develop, produce, and sell products and services that offer outstanding customer benefits and contribute significantly to improving customer loyalty thanks to their zero-defect quality. That is why we are proud of what we do. This also means that products and services are only provided or supplied to customers if we are convinced that they deliver the required and promised customer benefits, if they function perfectly, and are fault-free.

We want to promote a positive error culture that sees errors as an opportunity for improvement.
Everyone makes mistakes, but it is essential to correct them and learn from them. In our culture, no one is blamed or reprimanded for an error; but mistakes must not be repeated and, most importantly, must not be covered up! On the contrary, all of our employees are responsible for exposing and eliminating mistakes. Potential errors and possible sources of error are searched for, identified, and prevented using appropriate procedures and systems.

If an error leads to a customer complaint, our highest priority is to restore customer satisfaction. Like errors, complaints also provide an opportunity for improving our products and our understanding of customers. If, despite our best efforts, we are unable to restore our customer’s trust, we must use this lesson learned to discover and recognize the causes, and improve our future approaches.

We are reliable
We do what we say we are going to do. This applies both within our company and all the more so when dealing with our customers. All of our employees work closely together and we transfer unequivocal expertise at the right time. We provide accurate information in a responsible and timely manner. This is particularly important when working with our customers.
I am responsible for quality and continuous improvement.

I – and not just the others – am responsible for quality, continuous improvement, and customer satisfaction. As a company, we must constantly improve ourselves, our procedures, and our management system – and I play a key role in this process. What is good today may not be good enough tomorrow. In order to keep satisfied and loyal customers in the long term, we cannot rest on our laurels. That is why CIP, the continuous improvement process, plays a crucial role in our understanding of quality, determines our daily actions, and ensures our progress.

MULTIPARAMETR GAS MONITORING SYSTEM COMBINING A FUNCTIONALIZED AND A NON-FUNCTIONALIZED Microcantilever

ABSTRACT

We present a novel online gas monitoring system combining a pressure and a temperature sensor with two resonating microcantilevers from which one is functionalized with a highly sensitive hydrophilic material. By simultaneously observing eigen-frequencies and quality factors of the cantilevers gas density and viscosity can be determined as well as gas humidity in a sub-permille range. With this sensor information we can deduce molar concentrations of binary or even ternary gas mixtures in % together with the gas vapor ratio in a low ppm range.

Introduction

The aim of the presented sensor project is to develop a compact, robust and maintenance free gas monitoring system for industrial use in the field of inert gases e.g. welding or modified atmospheric packaging gas mixing application. In such applications typically binary or ternary mixtures of argon, helium, nitrogen, carbon dioxide, oxygen or hydrogen are used. Gas concentrations must be controlled with accuracies in the % range. In most cases, the humidity must also be monitored in these applications. Typical limit values are between 200 and 40 ppm [1]. The state of the art is the use of several different sensors in a sequence, e.g. thermal conductivity, together with specific optical absorption and dew point sensors. Such installations are bulky and require frequent recalibration. To bring the same functionality in one multiparameter sensor system we combine two resonating microcantilevers together with pressure and temperature sensors on one PCB board that is exposed to the process gas.

Commercially available silicon microcantilevers initially designated for atomic force microscopy are used (see Fig. 1). One cantilever is used to measure the density and the viscosity of the gas as reported by Badarlis et al. [2] or Huber et al. [3] and the other to measure water vapor in low concentration by adding a functionalized hydrophilic surface layer as reported for example by Urbiztondo et al [4].

Quality monitoring of fuels

Quality monitoring of fuels

Quality monitoring of fuels

The density of a liquid depends on its composition. If different liquids are mixed, the correct mixing ratio can be checked with density measurements. For example, in the case of heating oil: according to legal requirements, 7 % biodiesel may be added to heating oil. As this is tax-free, it is often operated at the limit of legality. With the density sensor DLO-M1 from TrueDyne, they monitor the quality of the fuel oil during the running process.
1. tank truck for the supply of fuel oil. 2 The sensor measures the density of the fuel oil directly at the transfer point. The data collected on site shows whether the correct media are being refueled in the correct ratio. 3 The product is handed over to the customer. Good quality is guaranteed.

Sensors for this application

Density sensor DLO-M1 for liquids

The DLO-M1 sensor measures the density of liquids in a microelectromechanical system (MEMS system). Within the MEMS system, the liquid is directed to an omega-shaped microchannel, the so-called omega chip. This tiny silicon tube – it is hardly thicker than a hair – is vibrated for the measurement. The density of the medium to be measured can be derived from the natural frequency of this oscillation.

Mark Twain is said to have said: “Writing is easy. You just have to leave out the wrong words.” In our case it is a complete sentence that we can omit from the VLO-M1 viscosity and density sensor data sheet.

Until that was the case, we needed a lot of developer sweat, brain and endurance.

Now the time has come, and we can delete the following sentence from the data sheet in the chapter “Permissible media”:

Do not use aqueous media. –

With the current VLO-M1 viscosity and density sensors and the DLO-M1 density sensor, you can now also measure aqueous media.

Cooperation

Manufacturer & service provider:
Exchange of experience in density
measurement technology

«„Our measuring systems systems meet the highest standards of accuracy. With our partner and calibration expert, Testo lndustrial Services GmbH, we can continuously test and prove this quality requirement.
The measure­ ment results also help us to standardize our products for future calibration processes.“

Managing Director, TrueDyne Sensors AG

A close cooperation for reliable measurement results of density sensors

Over the last few years, TrueDyne Sensors AG has acquired a great deal of expertise and know-how in the field of micro sensor technology and vibrating systems. The density module from TrueDyne Sensors AG is a flexural resonator measuring system in the MEMS technology with a measuring channel in sub-millimeter size. Measuring systems like these enable numerous companies to expand and improve their products and production sequences within the process. The high accuracy, the extremely compact design and the real-time measurement play a central role in these density modules.

Testo lndustrial Services GmbH support the manufacturer of density sensors in ensuring these quality criteria. Because detailed measurements in an independent calibration laboratory ensure safety for the customer. The two companies – manufacturer and service provider, specialized in the field of flow, introduced a close cooperation project in 2018.

The goal – Cooperation
Testo & TrueDyne

The goal of the cooperation project was to have the DLO-M1 density sensor from TrueDyne Sensors AG verified, under laboratory conditions, by a manufacturer-independent calibration service provider. Above all, the main issue was to test the sensor‘s „suitability for everyday use“. This serves as the basis for recommending the density sensor to users of calibration systems.

Services provided by Testo Industrial Services GmbH

  • Provision of laboratory space and calibration test benches
  • Many years of know-how in the field of calibration technology
  • Definition of test procedures and measurement methods
  • Derivation of argumentation approaches based on the results

The procedure – Performance
of density measurements

Equipment used for the measurements:

  • Liquid calibration stand – Testo KKF80 MU ± 0.08 % F.S.
  • Temperature sensor 1/10 DIN
  • Pressure sensor ± 0.04 % F.S.
  • DLO-M1 density sensor – TrueDyne Sensors AG
  • VDI Heat Atlas 10th edition 2006, Dba14 Table 12. Kinematic viscosity of water
  • Density table according to NIST

The challenges
Factors to consider during density measurements

  • Measurement errors due to the smallest of temperature differences
  • Consideration of reference systems, e.g. density table for water, mineral content, compressibility of the medium
  • Reproducibility of the measurements for the comparison of measurement results

The result
Long-term use of measurement results

The cooperation project resulted in the successful verification of the DLO-M1 density sensor by the manufacturer-independent calibration laboratory Testo Industrial Services GmbH.

The following results can be derived:

  • The measurement results were very convincing. The density deviation was well clearly below ± 0.2 kg/m3, which leads to a measurement uncertainty of < 0.02 % of the measured value.
  • The measured values could be tested in a reproducible manner at various pressure levels.
  • The suitability of the DLO-M1 density sensor from TrueDyne Sensors AG is ensured for calibration systems.

Testo Industrial Services GmbH

Calibration service provider for more than 220 accredited calibration procedures

Testo Industrial Services GmbH is one of the leading calibration service providers in Germany. The calibration laboratory for flow meters performs manufacturer- and media-independent calibrations for liquids and gases. As the field of calibration is extremely diverse, a wide range of test benches and calibrators are required. Testo uses seven self-developed test benches. These enable the calibration of different flow rates with very low measurement uncertainties.

TrueDyne Sensors AG

Manufacturer of density and viscosity sensors in sub-millimeter sizes

TrueDyne Sensors AG is a subsidiary of Endress+Hauser. With the company foundation in 2015, the main focus of competence was set on the development of smallest sensor technology. The heart of the technology is the OMEGA-chip, whose function is based on the flexural resonator measuring principle. The chip in the MEMS technology consists of a measuring channel in sub­ millimeter size and an integrated platinum temperature sensor for real-time on-board temperature measurement.
The measuring channel is hardly thicker than a hair and thus opens up new prospects for density measurement technology directly in the process.

VLO-P1 meter – IPA result

Mobile Density / Viscosity Meter

We congratulate Joel Becker on passing his EFZ electronics engineer exam as the best of his year!

TrueDyne: Joel, what was your thesis (IPA) about?
Joel: To complement the portfolio of TrueDyne Sensors AG, the density / viscosity sensor DLO/VLO-M1 is to be packed into a mobile solution. This should create a new application in which the density / viscosity sensor can be used.

In order to gain initial experience, a functional model was developed during the IPA, which packaged the proven density sensor into a handy and mobile solution. It was essential that the unique accuracy of the sensor be maintained, which enables the customer to achieve laboratory accuracy in the process.

The mobile density meter pumps the medium to be measured through the sensor developed by TrueDyne Sensors AG using a small peristaltic pump.

After the measurement, the measured values for density and viscosity as well as the calculated density according to API model are displayed at 15°C. This is done on a small 200×200 pixel E-Paper display.

During the IPA the complete power supply and battery monitoring as well as the control of the pump was realized. First a concept was developed, which was then converted into a schematic and finally into a finished printed circuit board.

Finally, the entire user interaction, i.e. operation and menu navigation, was developed and successfully programmed during the IPA.

TrueDyne: Why did you choose TrueDyne for your education?
Joel: I chose TrueDyne because of the many different challenges and the dynamic team.

TrueDyne: What did you enjoy most about your project?
Joel: What I liked most was the wide variety of tasks and project planning, but I also liked the software development (with a real-time operating system).

TrueDyne: What was the biggest challenge in your project?
Joel: The biggest challenge for me was the mechanics, because I’m more at home in electronics.

TrueDyne: What are your future plans?
Joel: In the near future I would like to study electrical engineering and stay a TrueDude.

TrueDyne: Thank you very much for your commitment to TrueDyne Sensors AG and the interview. We are pleased that you will remain with our team even after completing your training. We wish you continued joy and success on your way.

Universal Robots 5 – IPA Result

Development Process Flow DGF

We congratulate Philipp Meier on passing his examination
to the electronics engineer (EFZ).

TrueDyne: Philipp: What was your thesis (IPA) about?
Philipp: My IPA was about developing a process flow. With the help of a collaborative robot (Universal Robots 5), the process of mounting a circuit board in a housing was automated.

To tighten the circuit board to the housing a screwing device was developed, which is supposed to tighten a nut from the opposite side with a certain torque. In the course of the work, this had to be electrically integrated into the robot control system.

The control and monitoring of the screwdriving device takes place via a microcontroller and additional peripherals. A finished microcontroller board was used.

The process was realized in such a way that a flexible number of sensors can be manufactured (1-12 pieces).

The focus of the work was the software on the microcontroller and the robot. The robot programming was implemented with the already existing software tool.

Finally, the finished system was put into operation and tested at the IPA.

TrueDyne: Why did you decide to have your education at TrueDyne Sensors AG?
Philipp: The working atmosphere and helpfulness impressed me very much right from the start.

TrueDyne: What did you enjoy most about your project?
Philipp: I really enjoyed designing the brackets. Also the complete assembly of the system.

TrueDyne: What was the biggest challenge in your project?
Philipp: The biggest challenge was programming the robot. Precisely controlling the various components proved to be very time-consuming and laborious.

TrueDyne: Thank you very much for your commitment at TrueDyne Sensors AG and the interview. We are pleased that you will remain with our team even after completing your education. We wish you continued joy and success on your way.

Winner – German Innovation Award 2019

Winner – German Innovation Award 2019

We made it!  –  German Innovation Awards Winner 2019

The German Innovation Awards honour products and solutions across sectors, which differ from previous solutions mainly by being user-centred and offering added value. They do so because there are innovations in all sectors that shape the future and improve life. Sometimes you see them at first glance – but often not. The German Innovation Awards aim to change that. They make great achievements visible to a wide audience and ensure successful positioning in the market.
We are proud to have won the German Innovation Award with our newly developed gas density sensor DGF-I1.

The gas density sensor DGF-I1 of TrueDyne Sensors AG combines smallest sensor Technology (MEMS = Micro Electro Mechanical Systems), physical models and highest calibration competence on smallest size. With our sensor, we redefine the state of the art and offer our customers added value in places where measurement has not been possible until today, e.g. in quality monitoring for food packaging. Our measuring system is based on a micro tuning fork, which is set into vibration. The resulting resonance frequency of the tuning fork depends on the density of the surrounding medium. Due to the possibilities of MEMS technology and the sensor technology based on it, the quality

Measure the density of a gas directly in the gas line or in the gas tank: This is made possible by the DGF-I1 density sensor from TrueDyne. At the heart of the sensor is a microelectromechanical system (MEMS) with an oscillator in the form of a tuning fork. For the measurement, the metal housing surrounding the MEMS is filled with the medium. The natural frequency of the oscillator varies depending on the density of the gas surrounding it. In order to compensate for temperature effects, a platinum resistor which precisely measures the local temperature is built into the sensor.
The sensor is very compact with a diameter of 31 mm and a length of 63 mm and can be placed in even the smallest of spaces. It is screwed directly into the gas line or the gas tank with the integrated connection, and a filter protects against contamination. The measured values are transmitted to the higher-level system via an RS485 interface. The response time of 5 seconds enables density measurement directly in the process – the measurement does not have to be interrupted.

Monitoring of welding gas mixtures
Monitoring of pure gas
Monitoring of gas mixtures for food packages
