Description

These capacitive humidity transducers are conceived for the most common applications in heating, air conditioning, and ventilation technology. They distinguish themselves through their high measuring accuracy, excellent long-term stability, and good chemical resistance.
In case of CO2 measuring probes, a proven infrared technology is used. The used NDIR procedure (non-dispersive infrared technology) utilizes a patented auto calibration function and eliminates all aging effects.
The different combination possibilities between the process variables humidity (RH), temperature (T), and carbon dioxide(CO2) as well as the optically pleasing and easily installable cases set new standards in HKL technology.
The measuring probe in the indoor, wall-mounted, or rod version allow for a very broad field of application. For the respective process variables standardized current and voltage outputs are available. For temperature, passive resistance outputs can be delivered as an option. Measuring probes in the indoor version can also be equipped with an optional LCD display that shows the respective measured values in alteration. If, however, only a simple display of the process variables is needed then the battery-powered tabletop/wall-mounted indicator is the ideal solution.
Applications can be found in all areas of ventilation technology and in building management. Examples are residential buildings, office buildings, public buildings, storage halls, and production halls.
The humidity transducers of "version A" have performed particularly well in fields that have high demands on humidity measuring technology (e.g. greenhouses, swimming pools, or stables). In addition, the devices are also very suitable for outdoor use and in meteorology. Here, we recommend the radiation protection that is available in the accessories as it supplies the appropriate forced ventilation. Another available accessory is sensor coating. In many cases it enables improved or even permanent operation in atmospheres that are especially polluted.
