Pendulum humidity transmitter with display 4-20 mA

Our pendulum humidity transmitter with 4-20 mA current output and display has a robust plastic housing with quick-release screws. The device measures both humidity and optionally temperature, with four switchable measuring ranges available. The relative humidity is recorded by a digital humidity sensor, which is housed in a plastic sintered filter and attached to the housing with a two-meter cable. The two-line display shows either the humidity or the temperature in large format.

Pendulum humidity transmitter - Important assembly instructions
					For an accurate measurement of the humidity and temperature in the room, it is important to take the temperature dynamics into account. Air circulation should not distort the measurement. For this reason, the transmitter should be installed away from objects or obstacles that shield air movements. Please also avoid uncontrolled air currents (draughts) and uncontrolled solar radiation by installing the device near doors or windows (or other heat sources).
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.
