Siemens Building Technology QAC3171 Sensor
The Siemens QAC3171 is a professional-grade active outdoor temperature sensor designed for high-performance environmental monitoring in commercial HVAC and building automation systems. Engineered with a Pt1000 sensing element, this unit provides high measurement stability and linear signal transmission. It features a versatile 4-20mA output signal, making it compatible with a wide range of controllers for applications like outdoor air reset, chiller optimization, and weather-compensated heating control. The IP65-rated polycarbonate enclosure ensures the internal electronics remain protected against dust and moisture in harsh environments, while the screw terminal block allows for secure, reliable field wiring without specialized tools.
For optimal accuracy, mount the Siemens QAC3171 on the coldest wall of the building (typically the North side) at least 2.5 meters above the ground. Avoid locations exposed to direct morning sun, air vents, or balconies that could create localized heat pockets. This outdoor air temperature sensor supports multiple measuring ranges—including the standard -58°F to 122°F (-50°C to +50°C)—which can be field-adjusted via internal shorting plugs to match specific site requirements. Its loop-powered design simplifies installation, requiring a stable DC 13.5 to 35V power supply to maintain signal integrity over long cable runs.
Key Benefits for Contractors:- Pt1000 precision: Ensures accurate environmental temperature monitoring with minimal drift over time.
- Industrial Durability: The IP65 housing and weather-resistant probe are built to withstand extreme climates.
- Flexible Signal Output: Standard 4-20mA temperature transmitter interface integrates seamlessly into Desigo, Apogee, and third-party PLCs.
- Selectable Ranges: Adjustable internal jumpers allow for customized scaling (e.g., 0 to 50°C or -35 to 35°C) to increase resolution for specific climates.
- Easy Wiring: Features a terminal block connection and M16 cable gland for efficient surface or concealed installation.
- How do I test the sensor output in the field? You can move the internal shorting plug to the horizontal "test" position to force a specific output value, allowing you to verify the controller calibration without waiting for ambient temperature changes.
- What gauge wire should be used for the 4-20mA loop? We recommend using twisted-pair shielded cable (typically 18-22 AWG) to minimize electromagnetic interference, especially on longer runs.
- Can this be used as a room sensor? Yes, the Siemens QAC3171 is designed with high-end aesthetics and accuracy that allow it to be utilized as a heavy-duty room sensor in commercial spaces.
