Our channel humidity transmitter with 4-20 mA current output offers a robust plastic housing with a practical snap-on lid. The device reliably measures humidity and optionally temperature, with four switchable temperature measuring ranges available. The relative humidity is precisely measured by a durable, digital humidity sensor housed in a robust plastic sintered filter. The transmitter can be calibrated and enables fine adjustment for maximum accuracy. Installation is simple and is carried out directly in the ventilation duct using the mounting flange included in the scope of delivery.

To minimize measurement errors due to heat dissipation, place the probe shaft in the middle of the duct and make sure that the probe can be easily removed if necessary. | ||||||||||||||||
The device should only be used in pollutant-free, non-condensing air (< 95 % RH). The sintered filter protects the humidity sensor in outdoor and duct probes from dust, which can falsify the measurement result. Maintenance in the event of contamination is therefore important. Avoid touching the humidity element to prevent incorrect measurements. | ||||||||||||||||
Please lay the cable with a spare loop (5) and in such a way that no water can penetrate the sensor head. This allows you to extend the probe without disconnecting the electrical connection. | ||||||||||||||||
