Siemens Building Technology QAM2012.750 Temperature Sensor
The Siemens QAM2012.750 is a professional-grade duct averaging temperature sensor designed for precise climate monitoring in large-scale air handling units and ductwork where temperature stratification occurs. Featuring a highly stable 1k Ohm Platinum RTD (Pt1000) sensing element with a 385 alpha coefficient, this unit ensures repeatable accuracy of +/-0.75°F at 75°F across its extensive -40°F to 180°F operating range. The sensor utilizes a 24-foot flexible probe for comprehensive cross-sectional air measurement, making it ideal for integration with North American building automation systems (BAS) and controllers that require a passive resistance output signal.
Built for the rigors of mechanical rooms, the QAM2012.750 features a standard 2x4 inch galvanized steel electrical box housing for secure mounting and protection of wire leads. The flexible probe construction allows for versatile routing across the duct face to capture a true average temperature, eliminating the inaccuracies common with single-point sensors in large supply or return air streams. This duct temperature sensor is a direct-fit solution for contractors looking for reliability in commercial HVAC control systems.
Key Benefits- Enhanced Precision: The 1k Ohm Pt RTD sensing element provides superior accuracy and long-term stability compared to standard thermistors.
- Extensive Coverage: A 24-foot flexible probe allows for effective averaging across large duct cross-sections, preventing false readings from thermal pockets.
- Rugged Construction: Equipped with a galvanized steel enclosure and durable probe material to withstand high-velocity airflow and industrial environments.
- Seamless Integration: Compatible with most major building automation controllers due to its standardized passive resistance output.
What is the advantage of a 24-foot averaging probe?
In large ducts, air temperature is rarely uniform. A 24-foot probe spans the entire duct area to provide a weighted average, which is critical for accurate economizer control and freeze protection.
How do I wire the Siemens QAM2012.750?
This sensor uses a simple 2-wire lead connection. As a passive RTD, it is not polarity sensitive, making it straightforward to land on resistance-input channels on your controller.
Does this sensor require a specific mounting flange?
While it mounts directly to the duct using the integrated electrical box, an optional AQM2000 mounting flange can be used for added stability and a better seal at the insertion point.
