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 independent of these influences.

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

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

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

Absolutely. The system monitors critical parameters for PA6 quality: residual monomer content, water content, and impurities. It supports the compliance with ISO standards and enables the continuous documentation for quality certificates. This is especially important for automotive and textile applications.

Our sensors work reliably in a temperature range from -40 °C to 200 °C and pressures up to 500 bar. Through various material options such as stainless steel, Hastelloy, or PFA coatings, aggressive media can also be measured. Ex 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 customer-specific adaptations such as sensor lengths up to 3000 mm, special alloys for corrosive media, and various protection types, such as optional Ex protection. Each sensor is individually according to your requirements configured.

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

Yes, SensoTech manufactures sensors individually according to customer requirementsAll standard flanges, any installation lengths, 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 attacked. Regular calibration is not required - the sensors remain stable for years.

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

The system provides results in real-time. Over 30 measurements per second are performed. Based on these measurements, you get a current 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 high-precision 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.
