TR 158 – with magnet, -30 °C to 150 °C

These resistance temperature sensors with a cable and thermocouple temperature sensors with a cable, are designed to measure the surface temperature of ferromagnetic objects. The maximum temperature range of use of the sensors is -30 to 150 °C. To mount the sensor correctly, the measured surface must have a minimum diameter of 28 mm. The structure of the sensor ensures quick response to changes in temperature, if silicone grease or thermally conductive paste is applied between the measured surface and the sensor.

The sensors are designed for use in a chemically non-aggressive environment. the method of use must be chosen with regard to the temperature and chemical resistance of the case and lead-in cable.
