Wall Sensor AFTF Temp & Humidity
ON-WALL- HUMIDITY- AND TEMPERATURE SENSORS AFTF–MB Calibratable outside humidity and temperature sensor AFTF, detect the relative humidity (0…100% RH) and the temperature (–35…+80 °C), including various parameters in the humidity measurement. Applied in clean air and non-aggressive, dust-free environment. With a Modbus connection in a resistant IP65 plastic housing and M20 cable gland for cable connection, with quick-locking screws and an exchangeable plastic sinter filter. International SI units (default) can be changed to imperial (via Modbus). Measuring range: 0…100 % RH (humidity) / – 35…+80 °C (temperature) Medium: clean air and non-aggressive, non-combustible gases Deviation, humidity: typical ± 2.0 % (20…80 % RH) at +25 °C, otherwise ± 3.0 % Deviation, temperature: typical ± 0.4 K at +25 °C / ± 77 °F Zero point offset: ± 10 % RH (humidity) / ± 5 °C (temperature) Power: 24VAC (± 20%) / 15…36VDC – 24DC <1,2W Operation temperature: –30...+70 °C / –22...+158 °F T3-IP65 plastic housing with two M20 cable glands Housing dimensions: 108 x 78.5 x 43.3 mm / 4.25 x 3.1 x 1.7 in
