Airflow Sensor KFTF Temp & Humidity
DUCT HUMIDITY- AND TEMPERATURE SENSORS KFTF-MB Calibratable duct humidity and temperature sensor KFTF-T3 (± 2.0%) with Modbus RTU connection, in a resistant IP65 plastic housing with quick- locking screws and M16 cable gland for cable connection and a plastic sinter filter (exchangeable). Including mounting flange to detect the relative humidity (0…100% RH) and the temperature (–35…+80 °C) inside a tube, including various parameters in the humidity measurement. 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 (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 ± 0.2 K at +25 °C 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
