Product details about "TEMPERATURE SENSOR WITH 4-20 mA OUTPUT KNS ​​500"

The KNS 500 temperature sensor is designed to measure the temperature of gaseous substances in areas protected against water. In the application segment of railway vehicles, it is used to measure the temperature in the passenger compartments of train units and wagons and is part of the temperature control system.

The temperature sensor consists of a plastic ribbed head, on which is placed a printed circuit board with a temperature-current converter and a resistance temperature sensor. The sensors can be used for all control systems compatible with the current output from 4 to 20 mA. The standard temperature ranges of the sensor are given in the technical parameters table, while the maximum temperature around the sensor head is 80 ° C. The sensor complies with the protection class IP 30 according to EN 60529. A Appropriate design and high-quality material ensure that the sensors are not disturbing, even in interiors with high aesthetic requirements. You can choose the color of the box white or gray.

The sensor is designed to operate in a chemically non-aggressive environment.
