Outdoor humidity sensor

HYGRASGARD® outdoor humidity sensors precisely measure the relative humidity of the ambient air outdoors. They are designed for use in weather-protected outdoor zones, industrial plants and climate monitoring systems. The recorded values are output as a standard signal (0-10 V or 4...20 mA), depending on the version. Some models also offer a potential-free changeover contact output for direct switching functions - ideal for building automation and HVAC technology.
