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 affected 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 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.

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

The system provides real-time measurement values. Based on the measurements, you receive an updated measurement value every secondThis 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 way, the influence of temperature on the measurement can 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 barThrough 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 custom adaptations such as sensor lengths up to 3000 mm, special alloys for corrosive media, and various protection types, such as optional explosion protection. Each sensor is individually configured according to your requirements configured.

Yes, through multi-frequency measurements and special algorithms, various silane couplers such as aminosilanes, epoxysilanes, or vinylsilanes can be selectively measured. In multi-component systems, in addition to the speed of sound, a second physical quantity (e.g., conductivity) is used for the measurement.

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, various installation lengths (up to at least 1000 mm, further lengths on request), different threads, and special geometries for crystallization containers or small pipelines are available.

The sensors are available in various material and media-resistant versions, including stainless steel and Hastelloy as well as chemically resistant coatings and plastics such as PFA, PVDF, and ETFE. This allows them to be reliably used in a wide range of liquids and demanding process environments.

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