Description
The Honeywell C7021R2018 is a professional-grade NTC Type II temperature sensor engineered for accurate averaging duct and discharge air temperature measurement in commercial and light commercial HVAC systems. With a 24-foot insertion element, this sensor captures a true average temperature reading across the full duct cross-section, eliminating hot and cold spots that single-point sensors can miss — delivering the precise data your building automation or zone control system needs to maintain comfort and efficiency.
Key Features
- NTC Type II thermistor technology for accurate, reliable temperature measurement
- Averaging duct and discharge air sensing configuration
- 24-foot flexible insertion element for full duct-width coverage
- 10k Ohm resistance output for broad controller compatibility
- Wide operating temperature range: -40°F to 250°F (-40°C to 121°C)
- Designed for use with Honeywell and compatible building automation controllers
- Durable construction suited for demanding commercial HVAC environments
Application
The C7021R2018 is ideal for air handling units, rooftop units, and ducted systems where accurate supply or discharge air temperature averaging is critical. The long 24-foot sensing element threads through the duct to sample air temperature at multiple points simultaneously, providing a reliable averaged signal to the connected controller for precise system operation.
