Product features TEMPERATURE, RELATIVE HUMIDITY, CO2, PRESSURE AND VOC SENSORS - MODBUS RS 485 KSTHCPV 102
Temperature, Relative Humidity, Atmospheric Pressure, CO2 and VOC Sensor - KSTHCPV 102 is designed to measure carbon dioxide concentrations, air temperature, relative air humidity, atmospheric pressure and 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 KSTHCPV 2 temperature, relative humidity, atmospheric pressure, CO102 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 bus RS 485. Temperature, relative humidity, atmospheric pressure and VOCs are measured by a common internal sensing element whose signal is processed in a microprocessor and converted into a MODBUS RTU output signal. The CO2 value is measured by an NDIR module whose digital signal is also converted into a MODBUS RTU output signal - For the CO2 concentration sensor, there is an auto-calibration function available to set the sensor to the CO2 value minimum corresponding to the outdoor concentration level. The KSTHCPV 2 temperature, relative humidity, atmospheric pressure, CO102 and VOC sensor meets the protection index IP 30 according to standard EN 60529, as amended. The pleasant design and high quality materials ensure that the KSTHCPV 2 temperature, relative humidity, atmospheric pressure, CO102 and VOC sensor 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 KSTHCPV 2 temperature, relative humidity, atmospheric pressure, CO102 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 KSTHCPV 2 temperature, relative humidity, atmospheric pressure, CO102 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 individual sensors. Correct operation of the CO2 sensor requires the following operating conditions:
Ambient temperature around the sensor: 0 to 45 ° C
Ambient relative humidity: 0 to 95% (non-condensing humidity)
Atmospheric pressure: 87 to 110 kPa
