Airflow Sensor 8148 Temp&Humidity&500Pa
DUCT HUMIDITY-, TEMPERATURE- AND PRESSURE SENSORS ±500PA-MB Maintenance-free duct sensor covering humidity, temperature and pressure in one transducer. Microprocessor-controlled with Modbus RTU connection in a resistant IP65 plastic housing with quick-locking screws and M16 cable gland for cable connection. Including mounting flange to detect the relative humidity (0…100% RH) and the temperature (–35…+80 °C) inside a tube, with an exchangeable plastic sinter filter. A differential air pressure (max. ± 500 Pa) with connection nozzles for pressure hose (Ø 6 mm). The duct sensor is applied in a non-aggressive and dust-free environment and is suitable for installation in ceilings, ducts and devices. International SI units (default) can be switched to Imperial (via Modbus). Measuring range: 0…100 % RH (humidity) / – 35…+80°C /-31… +176°F (temperature) Medium: clean air and non-aggressive, non-combustible gases Deviation, humidity: typical ± 2.0 % (20…80 % RH) at +25°C/+77°F , otherwise ± 3.0 % Deviation, temperature: typical ± 0.2 K at +25 °C / ± 0.4 °F at +77 °F Pressure range: ± 500 Pa Accuracy: 500 Pa/2.0 inWC: typical ± 13 Pa at +25 °C / ± 0.05 inWC at + 77 °F Above- # below-pressure: max. ± 50 kPa Power: 24VAC (± 20%) / 15…36VDC – 24DC <0,2W Operation temperature: –30...+70 °C / –22...+158 °F Media temperature –20...+50 °C / –4...+122 °F IP65 plastic housing two M16 cable glands Housing dimensions: 126 x 90 x 50 mm / 4.96 x 3.54 x 1.97 in
