KNS 700
TEMPERATURE SENSOR WITH OUTPUT 0 to 10 V

Description and application

KNS 700
TEMPERATURE SENSOR WITH OUTPUT 0 to 10 V

The KNS 700 temperature sensor is designed to measure temperature of gaseous substances in spaces protected against water. In the application segment of Railway Vehicles, it is used to measure temperature in passenger compartments of train units and carriages and is a part of the temperature control system.

The temperature sensor consists of a plastic ribbing head, where a printed circuit board with a temperature–voltage converter and a resistance temperature sensor is placed. The sensors can be used for any control systems compatible with the current output of 0 to 10 V. Standard temperature ranges of the sensor are shown in the table of technical parameters, while the maximum temperature around the sensor head is 80 °C. The sensors meet ingress protection IP 30 according to EN 60529 standard, as amended.

The sensor is intended for operation in chemically non-aggressive environment.
