SensoTech GmbH is a leading company in the field of process measurement technology based in Barleben, near Magdeburg, Germany. We develop and manufacture 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.

In contrast to 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 disrupted by temperature or gas bubbles, our ultrasonic method is independent of these influences.

The LiquiSonic® measurement technology also contains neither moving parts nor components that can wear out or be consumed. After installation, the measurement system is therefore 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 delivers measured values in real time. Based on the measurements, you receive an up-to-date measured 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 bar. Aggressive media can also be measured using various material options such as stainless steel, Hastelloy, or PFA coatings. Explosion protection for zones 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 custom adaptations such as sensor lengths up to 3000 mm, special alloys for corrosive media, and various protection types, for example optional explosion protection. Each sensor is individually according to your requirements configured.

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

Yes, by combining the speed of sound measurement with additional physical variables (e.g. conductivity), multiple components can be determined simultaneously. This also allows further additives to be monitored.

The system offers various digital interfaces (e.g. Profibus, Ethernet / IP, Foundation Fieldbus) as well as analog 4-20 mA outputs. The integration is carried out without problems via standardized protocols.

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

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