Siemens Building Technology QAE2012.005 Sensor
The Siemens QAE2012.005 is a high-precision immersion temperature sensor designed for demanding HVACR and hydronic applications. Engineered with a 1k Ohm Platinum RTD (385 alpha) sensing element, this unit provides critical data for building automation systems, ensuring tight control over hot and chilled fluid loops. The 2.5-inch 300-series stainless steel probe comes paired with a durable brass or metallic thermowell, allowing for seamless maintenance without the need to drain the entire piping system. Operating within a temperature range of 0 to 250 degrees Fahrenheit (-18 to 121 degrees Celsius), the QAE2012.005 delivers a highly accurate resistance output signal, maintaining ±0.54°F precision at freezing benchmarks. This non-display model utilizes standard lead connections for direct integration into universal controllers. Contractors frequently specify this Siemens building technology sensor for its reliability in closed-loop systems where thermal lag must be minimized for optimal plant efficiency.
Key Benefits of the Siemens QAE2012.005- Ensures accurate hydronic monitoring with a high-stability Pt RTD 1k Ohm sensor.
- Minimizes downtime via the included stainless steel thermowell for rapid sensor replacement.
- Withstands harsh mechanical rooms with a rugged, metallic housing and 2.5-inch insertion depth.
- Compatible with most major North American building automation systems and universal HVAC controllers.
- Optimized for fluid temperature sensing in both domestic hot water and chilled water piping.
What is the maximum pressure rating for the included thermowell?
The standard 300-series stainless steel well is typically rated for up to 500+ PSI, though actual limits depend on the specific installation fitting and water velocity. Always verify pipe pressure before high-pressure hydronic installs.
Can this sensor be used for potable water applications?
The sensor housing and well are designed for commercial HVAC loops. For domestic potable water, ensure all materials meet local "lead-free" plumbing codes; direct contact with the brass well components may require specific potable water certifications.
Is an external power supply required for the 1k Ohm RTD?
No, this is a passive resistance sensor. The connected HVAC controller provides a small excitation current to read the varying resistance as temperature changes.
