These resistance-type sensors are intended for contact surface temperature measurement. the sensors, which are available including the fastening strap are suitable for temperature measurements on piping. The sensor dimmensions make it possible to place the sensor even under the pipe insulation. The standard operating temperature range is -30 to 130 °C. The proper sensing element is constructed to be isolated from the ambient influence. 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.
