Product information "Sensor for air temperature and humidity"

Mela® humidity / temperature sensors are to be installed in a room representative of the climatic measurement, in the plant or in the device. The proximity of radiators, windows or external walls must be avoided. The stated minimum air velocities as well as the load adapted to the operating voltage at I output (diagram) should be observed. Deviations thereof can lead to additional measurement errors due to self-heating. The mounting position of the sensor is arbitrary. However, it should be installed in such a way as to prevent the penetration of water. Condensation and splash water do not damage the sensor, but lead to incorrect measurements until the filter is completely dried out. In order to maintain the immunity to interference in accordance with EN 61326-2-3, we recommend using a shielded cable to connect the sensors and to mount it in the enclosed cable socket of the sensor. The protective filters should be unscrewed carefully only for the purpose of checking the function with the dampening solution. Care must be taken that the high-sensitivity sensor element is not touched. Contaminated filters can be washed out in the unscrewed state as required. When re-screwing it must be taken into account that the sensor does not correctly measure again until the appliance has completely dried. Sensors 9 can be completely cleaned with distilled water. We recommend the wall bracket or the mounting plate as mounting aids. The Mela® dampening solution is suitable for simple function checking. Further information, which should be taken into consideration when using moisture sensors with capacitive sensor elements, can be found in the "Application notes for sensor elements".
