SensoTech GmbH is a leading company in the field of process measurement technology based in Barleben, near Magdeburg, Germany. We develop and produce innovative solutions for monitoring and optimizing industrial processes. Our specialization lies in the precise measurement of concentrations, densities, and other parameters in liquids - in real-time and directly during the process.

Unlike optical methods, which are influenced by color or turbidity, conductivity-based methods, which are sensitive to electrical conductivity, or density-based methods, which can be disturbed by temperature or gas bubbles, our ultrasonic method is independent of these influences.

The LiquiSonic® measurement technology contains neither moving parts nor components that can wear out or be consumed. Therefore, after installation, the measurement system is completely maintenance-free and drift-free.

The sensors offer digital signal transmission up to 1000 m and enable continuous inline measurement without sampling.

The system provides measurements in real-time. Based on the measurements, you get a current measurement value every second when monitoring
menthol in acetone. This fast response time enables effective process control and early detection of deviations.

Since the speed of sound, like all other physical quantities, is influenced by temperature, all our LiquiSonic® sensors are equipped with temperature sensors. This allows the influence of temperature on the measurement to be directly compensated Therefore, it is not necessary to integrate additional temperature sensors.

Our sensors operate reliably in a temperature range from -40 °C to 200 °C and pressures up to 500 barWith various material options such as stainless steel, Hastelloy, or PFA coatings, aggressive media can also be measured. Explosion protection for Zone 1 and 2 is also available.

Yes, our sensors are designed for extreme conditions. In addition to the extended temperature and pressure range, we offer customizations such as sensor lengths up to 3000 mm, special alloys for corrosive media, and various protection types, including optional explosion protection. Each sensor is customized to your requirements configured.

Our system uses ultrasonic transit time measurement to determine the speed of sound in the liquid. The speed of sound directly correlates with the acetone-mentholconcentration and allows measurement accuracies of ±0.05 wt%. The integrated temperature compensation ensures stable results even with fluctuating process conditions.

Yes, by combining the speed of sound measurement with additional physical quantities (e.g., conductivity), mehrere Komponenten can be determined simultaneously. This allows for the monitoring of additional additives.

The system offers various digital interfaces (e.g., Profibus, Ethernet/IP, Foundation Fieldbus) as well as analog 4-20 mA outputs. The integration is seamless via standardized protocols.

Yes, SensoTech manufactures sensors individually according to customer requirements. All standard flanges, any installation lengths (up to at least 1000 mm, further lengths on request), various threads, and special geometries for crystallization containers or small pipelines are available.

The system is completely maintenance-freeThere are no mechanical wear parts, seals, or optical windows that could be affected. Regular calibration is not required - the sensors remain stable for years.
