Siemens Building Technology QAM2012.045 Temperature Sensor
The Siemens Building Technology QAM2012.045 is a professional-grade duct temperature sensor engineered for precise air temperature monitoring in HVACR and building automation systems. Built with a 1k Ohm Pt RTD (Platinum 385 alpha) sensing element, this unit provides the high-level accuracy required for critical supply, return, and discharge air applications. The 18-inch rigid probe allows for deep insertion into larger ductwork, ensuring the sensor tip reaches the center of the airflow for a representative reading rather than measuring stratified air near the duct walls.
Designed for seamless integration with Siemens Desigo systems and other third-party BAS controllers, the QAM2012.045 converts thermal changes into a stable resistance output. The rugged construction features a standard 2x4 inch metallic junction box housing with 1/2-inch knockouts, suitable for industrial environments. With an operational range of -40°F to 180°F (-40°C to 82°C), this 1000 ohm RTD sensor is a reliable choice for maintaining setpoint precision in commercial air handling units and complex ventilation plants.
Key Benefits
- High Precision Sensing: The 1k Ohm Platinum RTD ensures long-term stability and minimal signal drift compared to thermistors.
- Extended Reach: An 18-inch rigid probe length is ideal for large-diameter ductwork where accurate core temperature measurement is essential.
- Universal Compatibility: The 385a output signal is a standard protocol compatible with the majority of North American HVAC controllers and DDC systems.
- Contractor-Friendly Installation: Includes a metallic handy box enclosure and lead wire connections for straightforward field wiring without specialized tools.
Common Questions
Can the QAM2012.045 be used for averaging in large plenums?
No, this is a point sensor. For ducts subject to significant temperature stratification, a flexible averaging sensor from the QAM series should be used instead.
What is the maximum temperature this sensor can withstand?
The sensing probe is rated for a maximum operating temperature of 180°F (82°C). Exceeding this limit may damage the Pt RTD element or housing.
Does this sensor require a specific power supply?
This is a passive RTD sensor; it does not require a separate power supply but relies on the excitation current provided by your Building Automation System controller.
