  • With current and voltage outputs as well as passive Pt100 temperature output
  • With fast-response capacitive humidity sensor

Applications

  • For versatile climatic applications and ventilation

Description

Humidity measuring probes of the 907020 series are especially designed for the most common air conditioning applications and ventilation.
The measuring probes measure the relative air 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. A downstream electronic circuit converts the capacity corresponding to air humidity, and produces a standardized current or voltage output signal.
The measuring probes are only designed for atmospheric pressure systems, not for aggressive gases. The sensing element is protected by a gauze filter as standard (not for the indoor version). The accessories include further exchange filters to allow the use of the transducers outdoors or under extreme conditions.
The measuring probes are non-condensing and guarantee reliable humidity measurements in a working range of 5 to 95 % RH. Versions with an additional temperature measuring range are available for extended applications.
In addition to the standard versions with standardized output signals from 4 to 20 mA or 0 to (1) 10 V, some versions also provide a passive Pt100 temperature output.
Different design types ensure simple and reliable mounting to suit application and location.
In particular the compact rod versions with connecting cable, which also come with an optional plug connector, are suitable for the most varied of applications. The range is complemented by a particularly sturdy version with a form J terminal head.
