Siemens Building Technology QAM2021.750 Temperature Sensor
The Siemens QAM2021.750 is a high-precision duct temperature sensor engineered for demanding HVAC applications requiring averaged air temperature measurements across large cross-sections. This nickel RTD sensor utilizes a Ni 1000 element specifically calibrated for an output signal of 1k Ohm at 70°F, ensuring seamless integration with legacy Johnson Controls (JCI) systems and modern building automation controllers. Featuring a 24-foot flexible probe, the sensing element provides an accurate representative average in stratified airflows, preventing localized temperature swings from triggering short-cycling. Built for durability, the 24-foot probe operates within a temperature range of -40°F to 180°F (-40°C to 82°C). The unit is designed for efficient field installation with a lead connection type and no integrated display, making it a reliable choice for HVAC air temperature sensing in commercial air handling units and return air ducts.
- Flexible 24-Foot Probe: Allows for comprehensive averaging across large duct areas to eliminate measurement errors from air stratification.
- JCI Compatible Output: The Ni RTD 1k Ohm @ 70F curve ensures direct compatibility with specific field controllers without recalibration.
- Wide Environmental Tolerance: Operates effectively in extreme conditions ranging from sub-zero temperatures to high-heat return air.
- Industrial Build Quality: High-grade Siemens building technology construction ensures long-term signal stability and resistance to mechanical vibration.
Common Questions
How do I install an averaging sensor for maximum accuracy?
For the Siemens QAM2021.750, the flexible sensing element should be routed in a serpentine pattern across the duct cross-section, secured with mounting clips to ensure the entire air stream is sampled equally.
Can this sensor be used in high-humidity environments?
Yes, the probe is designed for standard duct applications; however, ensure the duct temperature sensor housing is properly sealed to prevent moisture ingress into the wiring compartment during high-load cooling cycles.
What is the difference between a point sensor and this averaging sensor?
A point sensor measures temperature at a single location, which can be inaccurate in large ducts due to stratification. The flexible 24-foot probe on this model averages the temperature along its entire length for a more precise system input.
