Description
Hygro transducers of the 907020 series are specially designed for the most common air conditioning applications and ventilation.
The transducers measure the relative humidity by means of a humidity dependent capacitor. This capacitive sensing element consists of a support plate carrying the electrodes, covered by a hygroscopic polymer film. This polymer film absorbs or releases water molecules from the medium being measured (air), thereby changing the capacity of the capacitor. An electronic circuit converts the capacity corresponding to humidity, and produces a standardized current or voltage output signal.
The transducers are only designed for atmospheric pressure systems, not for aggressive gasses. As standard, the sensing element is protected by a gauze filter (not for the indoor version). The accessories include further exchange filters to allow the use of the transducers outdoors or under extreme conditions.The transducers are non condensing and guarantee reliable humidity measurements in a working range of 5 to 95% rel. hum. Available versions with an additional temperature measuring range allow extended applications.In addition to the standard versions with standardized output signals from 4 ... 20mA or 0 ... 10V, some versions also offer an output signal from 0 ... 20mA or a passive Pt 100 temperature output.Different designs ensure simple and reliable installation to suit application and location.
In particular the compact rod versions with connection cable, which also come with an optional plug connector, meet the most varied applications. The range is complemented by a particularly sturdy version with a J form connection head.
