Combined probe for temperature, relative humidity, atmospheric pressure and VOC - STHPV 104 se consists of a plastic head with ribs in which there is a printed circuit board with individual sensors and a converter to ensure communication via the CAN bus. The temperature, the relative humidity, the atmospheric pressure and the common internal sensor in measured VOC, whose signal is processed by the microprocessor and converted to a CANopen specification CiA DS 301 output signal. The temperature sensor, the humidity, the atmospheric pressure and VOC - STHPV 104 meet the protection level of the intellectual property 30 according to ČSN EN 60529, as amended. Pleasant design and quality materials guarantee temperature, relative humidity, atmospheric pressure and VOC sensor - STHPV 104 it does not interfere even in interiors subject to high aesthetic requirements. The recommended location for sensors de temperature, relative humidity, atmospheric pressure and VOCs - STHPV 104 is at a height of 1,5m on the interior wall, in the area where people move, away from sunny places and places affected by wall temperature, heat sources or lighting.
Temperature, relative humidity, atmospheric pressure and VOC sensors - STHPV 104 are designed to operate in a chemically non-aggressive environment. The method of use should be selected based on the temperature and chemical resistance of the sensor head and the individual sensors. The operating conditions to ensure the proper functioning of the sensor are:
- Temperature around the sensor: -30 to 70 ° C, briefly -40 to 80 ° C
- relative humidity: 0 to 95% (non-condensing)
- atmospheric pressure: 87 to 110 kPa
