Duct humidity transmitter high with display 0-10 V

Our channel humidity transmitter High with 0-10 V voltage output and display offers a robust plastic housing with quick-release screws. The device reliably measures humidity and optionally temperature, with four switchable temperature measuring ranges available. The relative humidity is precisely recorded by a digital humidity sensor housed in a durable plastic sintered filter. The two-line display shows either the humidity or the temperature in large format. 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.

Duct humidity transmitter - Important assembly instructions
Important assembly instructions					Installation using the mounting flange (included in the scope of delivery): Please ensure that the Ø of the mounting flange matches the Ø of the protection sleeve.
					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.
When connecting several probes to a common 24 V AC power supply, pay attention to the polarity to avoid short circuits. Please note that the voltage outputs are short-circuit-proof, but an overvoltage or the application of the power supply to the voltage output can destroy the device.
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.
