Relative humidity and temperature sensor AFTF-35-U/W

absolutewall-mount4-20 mA

On-wall humidity and temperature sensor HYGRASGARD® AFTF-35 Condensation-protected on-wall sensor HYGRASREG® AFTF-35 with active and switching output, housing made of impact-resistant plastic with quick-locking screws, cable gland, plastic sinter filter (replaceable), optionally with/ without display, for detecting relative humidity (0…100 % RH) and temperature (4 switchable measuring ranges, max. 0...+100 °C) as well as for determining various parameters of humidity measurement technology. The measuring transducer converts the measured variables into a standard signal of 0 - 10 V or 4…20 mA. The unit is specially designed for use in the high humidity range (95…99 % RH). A long-term stable, digital humidity and temperature sensor is used. Overtemperature prevents or hinders dew formation on the humidity sensor. A second, separate temperature measuring element is used to determine the actual relative humidity of the ambient air. The following measured variables are calculated internally from these parameters and are retrievable via output OUT3: absolute humidity, mixing ratio, dew point and wet bulb temperature (can be changed via DIP switch). The sensor is used in medical technology, refrigeration technology, control technology, air conditioning and clean room technology. The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible.
