Aaon P87140 duct temperature sensor OE231

Product Description

The AAON P87140 Duct Temperature Sensor is a precision HVAC thermistor designed for high-accuracy air temperature monitoring in HVACR control systems. This 10k ohm Type II thermistor directly replaces the Aaon OE231 temperature sensor, ensuring seamless integration with legacy AAON rooftop units and heat pump systems. Built for durability in high-airflow environments, it provides stable resistance output for precise discharge air temperature monitoring and efficient staging of heating or cooling cycles. This sensor helps prevent coil icing and ensures the unit operates within specified setpoints.

• Direct OEM interchange, fully compatible with Aaon OE231.
• High-accuracy 10k Type II thermistor for precise environmental control.
• Rugged probe design withstands duct velocities and moisture, suitable for Supply Air (SA) and Return Air (RA) applications.

Product Highlights

Reliable OEM-spec component for precise air temperature monitoring in HVAC systems, ensuring system equilibrium and preventing unnecessary compressor cycling.
