Siemens Building Technology QFA3100 Sensor
The Siemens Building Technology QFA3100 is an industry-standard room humidity sensor designed for demanding HVAC applications requiring precise monitoring and long-term stability. This unit features a 0-10Vdc output signal and covers the full 0-100% relative humidity range with a high 2% measurement accuracy, making it a reliable choice for critical environments such as laboratories, hospitals, and pharmaceutical facilities. As part of the Siemens Symaro sensor line, the QFA3100 utilizes a capacitive sensing element with a short response time to efficiently transmit humidity data back to building automation systems (BAS) and programmable logic controllers (PLC). The hardware is housed in a rugged enclosure for surface mounting and features a secure terminal block connection for simplified field wiring. Integration is straightforward for any veteran technician, as the sensor operates on a standard 24Vac or 13.5-35Vdc power supply, ensuring compatibility with most common HVAC control systems without the need for additional voltage regulators.
Key Benefits- High Precision Sensing: Delivers ±2% accuracy across the entire 0-100% RH range for superior environmental control.
- Universal Control Compatibility: The standard 0-10Vdc analog output ensures seamless communication with nearly any DDC controller or automation interface.
- Durable Construction: Engineered for reliability in demanding HVAC environments, including high-traffic rooms and industrial storage.
- Efficient Field Wiring: Equipped with a robust terminal block for secure 2-wire or 3-wire electrical connections.
- Application Versatility: Ideal for psychrometric calculations, enthalpy control, and maintaining strict humidity levels in critical manufacturing zones.
What is the typical power requirement for this sensor?
The QFA3100 is designed to run on a 24Vac or 13.5-35Vdc operating voltage, making it compatible with standard 24V Class 2 power circuits.
Can this humidity sensor be used for outdoor applications?
While the QFA3100 is primarily a room sensor, it can be mounted for outdoor use when installed with an AQF3100 radiation shield to protect the sensing element from direct environmental exposure.
Does this model include a local display?
No, the Siemens QFA3100 is the standard model without a display to maintain a low profile in commercial spaces. For versions with local readouts, technicians should look at the 'D' designated models in the series.
