Honeywell C7041C2003/U 20K Duct Temperature Sensor 18in Probe

The Honeywell/Niagara C7041C2003/U is a 20K ohm duct-mounted temperature sensor featuring an 18-inch probe designed for commercial HVAC and building automation applications. As a genuine Honeywell component, it is built to the quality standards expected in professional building management and life-safety environments, making it well suited for integration into duct systems where accurate ambient air temperature measurement is critical to maintaining occupant comfort and system efficiency.

Key features & benefits

• 20K Ohm Sensing Element — The 20K ohm thermistor resistance provides a well-defined temperature-to-resistance curve compatible with building automation controllers that accept this standard input type.
• 18-Inch Duct Probe — The 18-inch probe length allows adequate insertion depth into a wide range of commercial duct sizes, ensuring the sensor element is exposed to representative airstream temperatures rather than boundary-layer anomalies.
• Genuine OEM Component — Sourced directly as a Honeywell/Niagara branded part, ensuring compatibility and reliability within Honeywell and Niagara-based building automation and controls ecosystems.
• Commercial-Grade Construction — Designed for professional installation in commercial HVAC duct systems, supporting long-term deployment in demanding building environments with minimal maintenance requirements.
