Monitoring of pure gas
Sensor for this application
Measure the density of a gas directly in the gas pipe or in the gas tank: This is made possible by the DGF-I1 density sensor from TrueDyne. The heart of the sensor is a micromechanical system (MEMS system) with an oscillator in the form of a tuning fork. For the measurement, the metal housing surrounding the MEMS system 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 is built into the sensor, which precisely measures the local temperature.
