Siemens Building Technology QAA2212.EWSN Sensor

Siemens Building Technology QAA2212.EWSN Sensor

The Siemens Building Technology QAA2212.EWSN is a professional-grade Room Temperature Sensor engineered for high-precision environmental monitoring in commercial and industrial HVACR applications. This passive RTD sensor utilizes a Platinum 1k Ohm (385 Alpha) sensing element to provide stable and accurate resistance feedback to the building automation system (BAS). Designed with a clean, no-display white enclosure featuring the Siemens logo, it is ideal for installations where a tamper-resistant, low-profile wall-mount temperature sensor is required. The QAA2212.EWSN operates within a standard range of 32 to 122 degrees Fahrenheit (0 to 50 degrees Celsius), ensuring reliable data for climate control loops. Utilizing a heavy-duty terminal block for field wiring, this Pt1000 sensor facilitates a secure connection and fast response times due to strategically placed housing ventilation. It is fully compatible with any controller capable of reading a 1k Ohm Pt RTD signal, making it a versatile choice for retrofit or new construction projects.

Key Benefits
  • High Accuracy: The Platinum 1k Ohm RTD element offers superior stability and precision compared to standard thermistors.
  • Universal Compatibility: Standardized 385a output signal ensures seamless integration with Siemens Desigo and other third-party BAS controllers.
  • Professional Aesthetics: The sleek, no-display design prevents unauthorized adjustments and maintains a clean architectural look.
  • Durable Construction: NEMA 1 rated enclosure with easy terminal block access for efficient field termination by technicians.
  • Optimized Airflow: Engineered ventilation slots maximize air circulation around the element for rapid detection of temperature changes.
Common Questions

What is the sensing element used in the QAA2212.EWSN?
This model uses a Platinum 1k Ohm RTD with a 385 coefficient, which is industry-standard for precision temperature measurement in commercial HVAC systems.

Does this sensor require a dedicated power supply?
No, as a passive RTD sensor, it provides a resistance-based output signal and does not require an external power source to operate.

Can this be mounted on a standard electrical box?
Yes, the housing is designed for direct mounting to a standard 2" x 4" electrical box or directly to drywall using the included hardware.
