The hydrogen sensor TCS (thermal conductivity sensor) is a compact measuring device, which is directly mounted on the measuring chamber by vacuum components.

The sensor is pre-thermostatted by its own electronics, whereby a very high stable sensor signal is ensured.

Originally developed for nitriding equipment of contract heat treatment workshops, the sensor is applicable for special measuring problems (e.g. low pressure application) due to a sophisticated calibration method.

Applications

In many technological processes, hydrogen plays a big role in achieving the desired product properties. By means of TCS, the hydrogen concentration can be monitored and/or provided to the process control via standard interfaces.

Due to the increasing adoption of quality management systems (e.g. ISO 9000), a constant monitoring and documentation of quality parameters becomes more important.

With the TCS, the user can monitor hydrogenous atmospheres efficiently and continuously.
