TrueDyne Sensors AG is one of the leading providers in the development of microsensor systems (MEMS systems). Their strength lies in microsensor technology and multi-parameter measurement technology. By combining these technologies in its sensors TrueDyne creates added value for its customers. They guarantee optimal performance by using new and well-known measuring principles in their unique compact sensors.
MEMS measurement systems open up new opportunities for customers to improve product quality, process reliability and productivity, thereby creating new sales and savings opportunities. TrueDyne sensor modules guarantee maximum performance in a compact design. Using ready-to-install, very small OEM measurement modules tailored to the customer's portfolio or installing a customer-specific solution - as an individual configuration, including connection to any operating environment, TrueDyne sensors serve a wide variety of industries: Oil & Gas, Power & Energy, Life Sciences and Food & Beverage.
Overall, every industry benefits from the application advantages of very precise density and flow measurements of the smallest volumes in the smallest of spaces. In other words: TrueDyne Sensors adds innovative microsensor technology to today's process measurement technology, creating added value through the consistent combination of the competence areas of microsensor technology and multi-parameter measurement technology.
The principles of the sensors from TrueDyne Sensors AG are based on microstructures vibrating in resonance. Thus, the TrueDyne Sensors AG sensors can measure density and viscosity on the basis of vibronic MEMS sensors. Contact with the media changes the resonance frequency, the vibration properties and the vibration quality of the structures. Density and viscosity can then be determined using physical models.
Density Sensor for liquids and gases
The DLO-M2 density sensor enables the density of liquids and gases to be monitored during the ongoing process, which means that analysis in a laboratory is no longer necessary. With the sub-millimetre measurement channel, the quality and properties can be monitored in the smallest of spaces.
- By combining density and volumetric flow data, one can determine the mass of a liquid. This application is possible, for example, in orifices, turbines or displacement devices.
- The density can be used to monitor the quality of fuel mixtures (such as E10 or biodiesel).
- Concentration monitoring of liquids: In the case of refrigerants, the concentration of liquids can be used to prevent them from freezing.
Viscosity Sensor for liquids
The viscosity sensor VLO-M2 determines the viscosity of liquids in an omega-shaped micro-channel. Viscosity data can be used to check the quality of liquids in an ongoing process. In addition to measuring viscosity, the VLO-M2 sensor records the density and temperature of the liquid.
- The process reliability can be increased by the viscosity.
- Viscosity plays a major role in engine oil calibration systems, for example.
- Viscosity helps to monitor the quality of fuels and lubricants.
Density sensor for gases
The DGF-I1 density sensor for gases not only measures the density with minimal quantities, but also determines the temperature and the pressure at the same time. This enables precise monitoring of the quality and determination of the concentration of binary gases.
- The density can be used to monitor the ratio of gas mixtures, which always ensures the correct gas mixture
By monitoring the gas composition based on density during the filling of food packages, the loss of food through sampling is eliminated
Checking of pure gases: The contents of a gas bottle can be checked based on the density. This makes it possible to check in the process whether the correct gas is being used
