Siemens Building Technology QFM3101 Sensor

Siemens Building Technology QFM3101 Sensor

The Siemens Building Technology QFM3101 is a high-precision duct relative humidity sensor designed for demanding building automation and HVAC control applications. Featuring a robust 4-20mA output signal, this sensor provides a linear 0-100% RH measurement with a strict ±2% accuracy rating. Engineered for professional-grade reliability, it functions as a direct functional cross for the HD2XMSX, ensuring seamless integration into existing control loops without needing recalibration of the controller logic.

Built for versatile field installation, the probe features an adjustable insertion depth ranging from 3.5 to 8 inches (90 to 206 mm), allowing for optimal positioning within various duct geometries to capture true laminar airflow readings. The unit is housed in an IP65-rated enclosure, making it suitable for environments where dust and moisture resistance are critical. Terminal block connections simplify wiring for field technicians, and the lack of an integrated display minimizes power consumption while maintaining a low-profile footprint in tight mechanical spaces.

Key Benefits for Contractors:
  • High-Accuracy Monitoring: Delivers precise ±2% RH data across the full 0-100% range for critical humidity control in data centers, laboratories, and commercial facilities.
  • Flexible Installation: The adjustable probe length and included mounting flange accommodate a wide variety of duct sizes and insulation thicknesses.
  • Industrial Build Quality: IP65 protection ensures long-term stability and sensor protection against contaminants in the airstream.
  • Simplified Retrofits: Standard 4-20mA 2-wire configuration is compatible with nearly all major building management systems (BMS).
  • Replaceable Sensing Tip: Optimized for maintenance-heavy loops where sensor debris or contamination requires rapid serviceability.
Common Questions:

Is the QFM3101 compatible with 24V AC power?
This model is designed for a DC supply voltage of 13.5 to 35V, typical for 4-20mA current loop configurations. Always verify your loop power supply before termination.

Can I use this sensor to measure temperature as well?
The QFM3101 is a dedicated duct humidity sensor. For combined humidity and temperature requirements, look to the QFM3160 or QFM3171 series.

Does this unit require field calibration?
No, the QFM3101 comes factory-calibrated. For high-precision applications, the removable sensing tip allows for easy replacement to maintain accuracy over time without removing the entire housing.
