The humidity sensor comes pre-adjusted from the factory thus making a time-consuming humidity adjustment unnecessary. The temperature measurement occurs using a highly precise thin-film element, a must for the exact determination of a dewpoint.
The DFN housing of the humidity sensor ensures maximum mechanical sensor protection and facilitates the processing using standard reflow soldering process. A protective film applied to the active humidity sensor surface ensures a protection against contamination such as dust, salt or chemical pollution.
Depending on the accuracy requirements and available evaluation electronics, different cost-effective evaluation circuitry is available for the humidity sensor – our specialists will be glad to assist you.

Transmitter with "two-wires" technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology "three-wires" the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
