THPPRO MODBUS Digital Sensor for Air Temperature, Humidity and Pressure

Mela® humidity/temperature sensors must be installed at a location in the room, system, or device that is representative of the climate measurement. Avoid proximity to radiators, windows, or exterior walls. The specified minimum air velocities and the load at the I output (diagram) adjusted to the operating voltage must be observed. Deviations from these values ​​can lead to additional measurement errors due to self-heating. The sensor can be installed in any position. However, it should be mounted in such a way that water ingress is prevented. Condensation and splashing water do not damage the sensor, but will lead to incorrect measurements until the filter is completely dry. To maintain interference immunity according to EN 61326-2-3 during use, we recommend using a shielded cable to connect the sensors and installing it professionally in the supplied cable socket of the sensor. The protective filters should only be carefully unscrewed for functional testing using the humidity standard. Care must be taken not to touch the highly sensitive sensor element. Contaminated filters can be rinsed out while unscrewed if necessary. When reattaching the sensor, please note that the sensor will only measure correctly once it has completely dried. Sensors 9 can be completely cleaned with distilled water. We recommend the wall bracket or mounting plate as mounting aids. The Mela® humidity standard is suitable for simple functional testing. Further information to be observed when using humidity sensors with capacitive sensor elements can be found in the "Sensor Element Application Notes."
