Hygro transducer and hygrothermal transducer (capacitive) 907020

Technical data

Hygro and Hygrothermal Transducers (Capacitive) for Air Conditioning Applications   • For measuring relative humidity and temperature • For versatile climatic applications and ventilation • Available in indoor, wall-mounted, and duct version • Compact rod versions with connecting cable or robust terminal head • With current and voltage outputs as well as passive temperature output • Optional indoor and wall-mounted version with two-line LCD display available   Designed for the most frequently used ventilation and air conditioning applications, these measuring probes are characterized in particular by their easy installation, robust form, and reliable humidity measurement technology. The relative humidity is recorded by means of a humidity-dependent capacitor. The capacitive sensor element consists fundamentally of a carrier plate upon which electrodes are placed and a hygroscopic layer of polymer over this. 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 signal. The measuring probes are only designed for atmospheric pressure systems and non-aggressive gases. They are non-condensing and guarantee a reliable humidity measurement for each working range. Versions are available with an additional temperature duct for extended application. The measured values are transferred by way of standardized output signals with 4 to 20 mA, 0 to 1 V, or 0 to 10 V at the subsequent electronics. Some versions are also optionally available with a passive Pt100 temperature output, which rules out costs for extended electronics. The new indoor and wall-mounted case was specifically designed to meet the requirements of the user with regard to ease of assembly and maintenance, as well as looking to optimize measurement technology. A separate, removable case bottom section with predefined mounting holes, which are also suitable for flush-mounted socket assembly, ensures, amongst other things, very simple installation of the indoor version. The simple but practical sealing system also enables easy opening and closing of the device without requiring a great effort. The robust wall case with increased IP65 humidity protection accounts for this requirement. For example, only a single screw is necessary here in order to secure the device. Both new variants can be delivered with a two-line LCD display, which enables the simultaneous display of current humidity and temperature measured values in the range of -30 to +60 (+80) °C depending on the version.
