Temperature, Relative Humidity, Atmospheric Pressure and VOC Sensor - The KSTHPV 102 is designed to measure carbon dioxide concentrations, air temperature, relative air humidity, atmospheric pressure and the concentrations of volatile organic compounds. In the segment of railway vehicle applications, it is used to measure all variables in passenger compartments of train units and wagons and is part of the control system for temperature, relative humidity, atmospheric pressure and air quality.

The KSTHPV 102 temperature, relative humidity, atmospheric pressure and VOC sensor consists of a plastic ribbed head containing a printed circuit board with the individual sensors and a converter to establish communication via the RS 485 bus. Temperature, relative humidity, atmospheric pressure and VOCs are measured by a common internal sensing element, the signal of which is processed in a microprocessor and converted into a MODBUS RTU output signal. The KSTHPV 102 temperature, relative humidity, atmospheric pressure and VOC sensor meets the degree of protection IP 30 according to CSN EN 60529. The pleasant design and high-quality materials ensure that the temperature sensor, Relative humidity, atmospheric pressure and VOCs of the KSTHPV 102 does not appear intrusive even in interiors with high aesthetic requirements. You can choose the color of the box white or gray. It is recommended to install the KSTHPV 102 temperature, relative humidity, atmospheric pressure and VOC sensor on an interior wall at a height of 1,5 m, in areas with moving people, not exposed to direct sunlight and not influenced by heat from walls, heat sources or lighting. The KSTHPV 102 temperature, relative humidity, atmospheric pressure and VOC sensor is designed to operate in a chemically non-aggressive environment; its use should be chosen according to the temperature and chemical resistance of the head and the individual sensors. Correct operation of the sensor requires the following operating conditions:

Ambient temperature around the sensor: -30 ° C to 70 ° C, for short periods -40 to 80 ° C

Ambient relative humidity: 0 to 95% (non-condensing humidity)

Atmospheric pressure: 87 to 110 kPa
