Siemens Building Technology QFA3160 Sensor
The Siemens QFA3160 is a high-precision room humidity and temperature sensor engineered for critical HVAC applications requiring rapid response times and long-term stability. This wall-mount RH sensor utilizes a capacitive sensing element to provide a 2% accuracy rating across a full 0-100% relative humidity range. Designed for seamless integration with building automation systems, it features simultaneous 0-10Vdc output signals for both humidity and temperature, ensuring reliable data transmission to any compatible Siemens Symaro or third-party controller. Professional contractors value the QFA3160 for its robust IP65-rated housing, which protects the internal 1K Platinum RTD temperature sensing element from environmental contaminants while maintaining a clean, no-display aesthetic for secure public or commercial spaces. The unit operates on a 24Vac or 13.5-35Vdc power supply and utilizes a standard terminal block connection for efficient field wiring. Whether managing economizer control, psychrometric calculations, or demanding indoor air quality (IAQ) monitoring in laboratories and hospitals, this sensor delivers the technical precision necessary for high-stakes environmental control.
Key Benefits for HVAC Professionals- Dual Signal Output: Provides independent 0-10Vdc signals for humidity and temperature via a single device, reducing wiring runs and BAS integration complexity.
- High Accuracy Standards: Maintains a strict ±2% RH tolerance and ±0.6 K temperature accuracy, making it ideal for pharmaceutical and cleanroom environments.
- Field-Proven Durability: Features an IP65 degree of protection with a specialized sensing tip designed for short response times and resistance to drift.
- Flexible Installation: Compatible with various mounting accessories, including the AQF3100 outdoor kit, and accommodates 24V AC/DC power configurations.
Which controllers are compatible with the QFA3160?
This sensor is compatible with any building automation system or PLC that accepts a 0-10Vdc analog input. It is standard for Siemens Desigo systems and widely used with other HVAC controllers from Kele, Johnson Controls, and Honeywell.
Does this unit require specific wiring for humidity-only use?
Yes. To ensure stable operation, the humidity output terminals (G1+ and I1-) must be powered even if you are only utilizing the temperature signal portion of the device.
Where should the sensor be mounted for the most accurate readings?
For optimal environmental sensing, install the unit approximately 1.5 meters above the floor on an interior wall. Avoid locations with direct solar radiation, proximity to heat sources, or dead-air zones behind curtains or shelving.
