Siemens Building Technology QAE2020.005 Sensor
The Siemens Building Technology QAE2020.005 is a high-precision immersion temperature sensor designed for demanding hydronic HVACR and building automation systems (BAS). Built for reliability in hot or chilled media, this sensor utilizes a 1k Ohm @ 32F (LG-Ni) nickel RTD sensing element to provide accurate resistance output to North American building controllers. With a 2.5-inch probe length and a 300-series stainless steel thermowell included, it is optimized for rapid thermal response and long-term stability in medium-flow piping applications.
Operating within a broad range of 0 to 250 degrees Fahrenheit (-18 to 121 degrees Celsius), the QAE2020.005 features a rugged metallic NEMA 1 enclosure and a pulling elbow for simplified field wiring via lead connections. Whether you are monitoring supply water temperatures or managing chiller plant optimization, this Siemens immersion sensor ensures HVAC temperature monitoring remains precise without the need for frequent recalibration. Its familiar installation footprint requires no special tools, making it a standard choice for mechanical contractors and service technicians looking for a Ni1000 immersion probe that maintains signal integrity across extended cable runs.
Key Benefits- Precision Sensing: Utilizes a 1k Ohm Nickel RTD (LG-Ni) element for highly accurate temperature feedback to Siemens and other compatible building controllers.
- Application Versatility: Suitable for both hot and chilled water applications, providing consistent performance across a wide 250°F span.
- Rugged Construction: Durable metallic housing and a stainless steel sensing pocket protect the element from pressure and corrosion.
- Installation Ready: Includes a 2.5-inch thermowell and features a standard 1/2-inch NPT mounting for immediate integration into hydronic loops.
Is the thermowell included with this model?
Yes, the QAE2020.005 ships with a 2.5-inch 300-series stainless steel thermowell as a complete assembly.
What is the signal output for the Siemens QAE2020.005?
This sensor provides a passive resistance output signal specifically calibrated to 1000 Ohms at 32°F (LG-Ni1000).
Can I use this sensor in potable water systems?
No, this immersion sensor is intended for hydronic HVAC applications and is not rated for use with potable water.
