Resideo Braukmann 50021579-001 Temperature Probe PT1000 Indoor Return Discharge Mixed Air Sensor

Product Description

The Resideo Braukmann 50021579-001 is a PT1000 temperature probe designed for indoor HVAC air monitoring applications. HVAC technicians and building automation professionals use this sensor to track return air, discharge air, and mixed air temperatures in commercial and light industrial systems. Accurate air temperature sensing is critical for system efficiency, comfort control, and equipment protection. This probe plugs into the measurement loop and sends a reliable resistance signal back to the controller, allowing the system to make precise adjustments based on real-time conditions.

The 50021579-001 uses a PT1000 sensing element. PT1000 sensors are platinum resistance temperature detectors that change their electrical resistance as temperature changes. They are known for stable, repeatable readings across a wide temperature range. This probe covers a range of -40 to 350 degrees Fahrenheit, making it suitable for a broad range of HVAC and air handling applications. Whether used on an air handling unit, a fan coil, or a rooftop unit, the probe delivers consistent performance in demanding environments.

The probe body measures 2 inches in length with a diameter of 0.25 inches. A 9 inches lead wire connects the probe to the controller wiring. This compact form factor makes installation straightforward in tight ductwork or panel locations. The 50021579-001 is compatible with Honeywell T775 Series 2000 controllers, a widely used line of electronic temperature controllers in commercial HVAC applications. Note that this probe is not intended for use with U Series controllers or NEMA 4 rated enclosure applications. Always verify controller compatibility before installation.
