External Temperature Sensor

These resistance temperature sensors are designed for measurement of outside air temperatures. The plastic head is equipped with a cable gland (the head has a terminal block) or a connector. The standard temperature range of these sensors is – 50 to 100 °C. The sensors can be used for all control systems that are compatible with the sensor types or output signals listed in the table of technical parameters. Easy installation of the temperature sensors is ensured thanks to the unique design of the ” S head ” of SENSIT sro. The temperature sensors are designed for operation in non-aggressive environments.
