At Innovative Sensor Technology IST AG we specialize in the  development and manufacturing of temperature sensors, thermal mass flow sensors, humidity sensors, conductivity sensors and biosensors.

In addition to our standard products, we offer sensor adaptations to individual, customer-specific application needs - right up to the joint development of new technologies. IST-sensors are characterized by their accuracy and consistency in various measurement conditions. They are used in measuring instruments for various applications, such as med-tech, process control, automation, aerospace, test and measurement or biotechnology.

New products

Moisture-in-Oil Sensor

Moisture-in-Oil Sensor

Fully calibrated, ready-to-use assembled RH/T module in screw-in assembly

Frequently, it is necessary to monitor the condition of lubricants with the support of sensor technology. For such a monitoring function, IST AG has engineered the new Moisture-in-Oil sensor, a compact, digital humidity and temperature module (RH/T) that will measure the relative degree of saturation of water in %RH (water activity aw in %) in oils and fuels.

SFS Flow Module news

SFS Flow Module

Ready-to-use, linearized mass flow module for gases

Fast, continuous gas flow monitoring, suitable for gas dosing systems, manifolds and analyzers, with a response time ≤  20 ms. The module is already linearized from factory with a reproducibility of 0.2 % and an accuracy of 2 %.

Humidity and temperature module HYT 939P with PTFE filter

HYT 939 P with VOC protection

Robust humidity and temperature monitoring in industrial settings

In industrial drying processes humidity measurement is vital in providing early warning of fluctuations in moisture content or for providing an indirect indication of how close dried materials are to their desired final moisture content.

IST AG’s HYT 939P with VOC protection provides the optimal solution for compact sensors in industrial drying applications.
