Features:
- extended temperature range;
- high reliability under the influence of vibration, shock, temperature, humidity;
- maintains operability when exposed to aggressive environments with a temperature of 600 °C due to the use of special alloys in the design;
- analog output;
- design has been developed that provides high vibration and shock resistance at the cable termination site.
Version: thermoelectric converter (TC) consists of a sensitive element placed in the housing, a cable jumper and a connector. The sensitive element is based on a thermocouple cable with mineral insulation TU 16-505.757.
