The KSTH 104 temperature and relative humidity sensor is designed to measure the temperature and relative humidity of the air in spaces protected from water. In the segment of rail vehicle applications, it is used to measure both variables in passenger compartments of train units and wagons and is part of the temperature and relative humidity control system.

The KSTH 104 temperature and relative humidity sensor consists of a plastic ribbed head where a printed circuit board with the individual sensors and a converter is placed to establish communication via the CAN bus. The temperature and relative humidity are measured by a common internal sensor, the signal of which is processed in a microprocessor and is converted into a CANopen output signal with the CiA DS 301 specification. The sensors meet the protection index IP 30 according to EN 60529. Appropriate design and high quality materials ensure that the sensor is not annoying, even in interiors with high aesthetic requirements. You can choose the color of the box white or gray.

The KSTH 104 temperature and relative humidity sensor is designed to operate in a chemically non-aggressive environment; its use must be chosen according to the temperature and the chemical resistance of the individual sensors. The operating conditions to establish correct operation are:

- Ambient temperature near the sensor: -40 to 80 ° C

- Ambient relative humidity: 0 to 95% (humidity without condensation)

- Atmospheric pressure: 87 to 106 kPa
