AF Outdoor relative humidity and temperature sensor

Calibratable outdoor humidity ⁄ temperature sensor (± 3 %) or (± 2 %)

with plastic sinter filter (optional metal sinter filter) or with pluggable metal sinter filter; terminal box enclosure made of impact-resistant plastic, with ⁄ without optional display. It measures the relative humidity and ⁄ or the temperature of the air and converts the measured into a standard signal of 0 - 10 V or 4...20 mA um. It has four switchable temperature ranges and is applied in non-aggressive dust-free atmospheres in refrigeration, air conditioning, ventilation and clean room technology. Relative humidity (in % r. H.) is the quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature. These measuring transducers are designed for exact detection of humidity. A digital long-term stable sensor is used as measuring element for humidity measurement. Fine adjustment by the user is possible.

Humidity: 0...100% r.H.,
Temperature: -35°C...+80°C
Output: 0-10V or 4...20mA
