Description
The Siemens Building Technology QFM2160U is a professional-grade duct-mount relative humidity and temperature sensor engineered for building automation and HVAC control applications. Featuring a 0–10 Vdc analog output for both humidity and temperature, this sensor integrates seamlessly with BAS controllers, DDC systems, and energy management platforms that require accurate, real-time duct air monitoring.
Key Features
- Dual-parameter sensing: measures both relative humidity (RH) and temperature in a single duct-mount device
- 0–10 Vdc output signal for RH (0–100% RH range) and temperature — compatible with most BAS and DDC controllers
- Adjustable insertion depth probe: 3.5 to 8 inches, accommodating a wide range of duct sizes and configurations
- Terminal block connection type for secure, tool-friendly field wiring
- No display model — ideal for installations where a local readout is not required
- Compact, durable housing designed for reliable long-term performance in commercial duct environments
