Sensor for measuring of temperature and humidity in ventilation ducts.
The sensor measures the temperature of the air in the duct by a NTC 22K sensor and humidity by a humidity sensor. The sensor is supplied with a mounting bracket, which can be used as a drilling template. After the holes have been drilled in the duct (18 and 5mm drills), the bracket and sensor is mounted with screws.
The sensor must be turned in such a way that the humidity sensor faces downwards (and the NTC sensor consequently faces upwards) – thereby ensuring that condensate, if any, does not rest on the humidity sensor but runs out of the sensor.
The same sensor without the mounting bracket can be bought – see art.no. 49332.
