These capacitive humidity measuring probes have been designed for the most common applications in heating, air conditioning, and ventilation technology. They particularly distinguish themselves through their high measuring accuracy, excellent long-term stability, and good chemical resistance. Modern case designs enable low installation costs and offer the greatest possible protection against pollutants and condensation. These factors, in turn, contribute towards smooth and trouble-free continuous operation.The CO2 measuring probes use proven infrared technology for measuring the carbon dioxide concentration. The NDIR procedure has a patented auto calibration function, eliminates aging effects, and as a result allows accurate measurement of the CO2 values with long-term stability.
Different combination options between the measurands carbon dioxide (CO2), humidity (RH), and temperature (T) in visually appealing and easy-to-install housing once again set new standards in heating, air-conditioning, ventilation technology, and in many other areas in which corresponding measurement technology is used. This series enables a broad spectrum of uses in indoor, wall-mounted, channel, and rod versions.
Standardized current or voltage signals are available as outputs. For some devices passive resistance outputs as well as a digital output are also available as an output option. Measuring probes in indoor and wall-mounted versions can be equipped with a digital display. Furthermore, a battery-operated tabletop and wall-mounted indicator is the ideal and cost-effective solution if only a simple display is needed.

Features:

For measuring relative humidity, temperature, and fresh air quality

  • Available in indoor, wall-mounted, channel, and rod versions
  • For applications in facility management as well as in areas of climate and ventilation monitoring
  • LCD display available as an option

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 air humidity is recorded by a humidity-dependent capacitor. The capacitive sensor element consists fundamentally of a carrier plate upon which electrodes are placed with a hygroscopic layer of polymer over the top. 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 ensure, among other things, very simple installation of the indoor version. The holes are also suitable for flush-mounted socket assembly. The simple but practical sealing system also enables easy opening and closing of the device without requiring a great deal of effort. The robust wall case with increased IP65 humidity protection accounts for this requirement. For example, only a single screw is necessary here 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.
