K160 Fast Response with a Metal Connection Head

These resistance-type sensors are intended for contact temperature measurements of liquid or gaseous substances. The structure of the sensor’s stem enables the sensor to be used for direct measuring of the temperature in ducts and ensures quick response of the sensor to changes in temperature. The standard operating temperature range is -30 to 130 °C. The sensors can be utilised for any control systems that are compatible with sensing element output signals or output signals quoted in the table of sensing element types.

The sensors are designed to be operated in a chemically non-aggressive environment
