Sensor for measuring the viscosity of liquids

Viscosity data can be used to determine the properties of liquids and monitor their quality. The sensor measures the viscosity in the running process – even in the smallest of spaces. Irrespective of the viscosity, the sensor also measures the density and temperature of the medium being measured.

Application examples:

• Optimization of process reliability in applications where a certain viscosity is required. For example, engine oils on calibration systems.
• To supplement the density values to ensure the quality of lubricants or fuels.

The VLO-M2_ex sensor for use in hazardous areas according to ATEX: II1G and IECEx: Zone 0 measures the density and viscosity 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

Thanks to measurement in the MEMS system, the sensor is only 30 x 83 x 15 mm in size and can be accommodated even in tight spaces. The high-precision measurement results are immediately available, allowing continuous measurement during the process.
