Description
The Siemens QAM2012.045 is a precision duct-mount temperature sensor engineered for building automation and HVAC control applications. Utilizing a Platinum RTD (Pt 1000 / 1k Ohm, 385α curve) sensing element, it delivers highly accurate and stable temperature measurement across a wide operating range, making it an ideal choice for air handling units, VAV systems, and commercial duct monitoring installations.
Key Features
- Sensing element: Platinum RTD, 1k Ohm, Alpha 385 (385a) output signal
- Temperature range: -40°F to 180°F (-40°C to 82°C)
- Probe style: 18-inch rigid probe for deep duct insertion and representative air sampling
- Connection type: Lead wire termination for straightforward field wiring
- No integral display — clean, low-profile installation
- Designed for compatibility with Siemens Building Technology controllers and third-party BAS platforms accepting Pt RTD inputs
Application
The QAM2012.045 is suited for supply air, return air, and mixed-air temperature sensing in commercial and light-industrial HVAC systems. The 18-inch rigid probe ensures accurate readings across the duct cross-section, while the Pt RTD element provides excellent long-term stability and repeatability compared to thermistor-based alternatives.
