SIEMENS QFA3171 Outdoor Humidity and Temperature Sensor

Precision Climate Control and Reliable Measurement with ORFA Industrial Assurance

Precise monitoring of outdoor conditions in industrial and commercial facilities is critical for energy efficiency and comfort. Developed by Siemens, the outdoor humidity and temperature sensor, model QFA3171, offers high accuracy and reliability. With an IP65 protection rating, this outdoor humidity and temperature sensor provides full protection against dust and moisture ingress, operating in harsh weather conditions. Using capacitive humidity sensing technology, the outdoor humidity and temperature sensor achieves an accuracy of ±2% r.h., while the Pt1000 temperature sensing element delivers excellent performance in temperature measurement. With a 4…20 mA active output signal, this outdoor humidity and temperature sensor integrates easily into building automation systems, serving as an outdoor temperature reference for energy management systems. The replaceable sensor tip AQF3150 reduces maintenance costs for the outdoor humidity and temperature sensor, which is ideal for outdoor mounting. Operating over a wide range (-40…+70°C, 0…100% r.h.), the device responds quickly to instantaneous changes. With its stainless steel components and UV-resistant material, the outdoor humidity and temperature sensor offers long service life, and two-wire connection simplifies installation. The sensor operates at 13.5…35 VDC with low power consumption, making it energy-efficient. The output signal for humidity and temperature is separate 4-20 mA, connectable to two different analog inputs. Manufactured with Siemens quality assurance, this outdoor humidity and temperature sensor is designed to DIN standards. The outdoor humidity and temperature sensor is available in ORFA Industrial stock and can be delivered immediately for your projects. By using an outdoor humidity and temperature sensor in your facility, you can optimize your HVAC systems and achieve energy savings.
