Honeywell C7041B2005 Temperature Sensor

For veteran commercial HVAC contractors, the Honeywell C7041B2005 Temperature Sensor remains the industry standard for precise duct temperature monitoring. This 20K Ohm NTC thermistor is engineered for high-accuracy performance within Honeywell Excel series environments, specifically the Excel 10, 50, 80, 100, and 500 controllers. Featuring a 6-inch stainless steel insertion probe, the sensor provides reliable, non-linearized resistance signals that allow for tight environmental control in air handling units and return air ducts.

Built with solid-state components that are naturally resistant to dust and debris, the Honeywell C7041B2005 operates across a wide range of -40 to 250 degrees Fahrenheit. It is housed in a rugged metallic junction box with accessible knockouts, simplifying field wiring in Building Automation Systems (BAS). Whether you are performing a HVAC sensor replacement or commissioning a new commercial system, this unit (interchangeable with the C7041B2005/U) ensures long-term stability with a nominal resistance of 20,000 ohms at 77?F, maintaining system compatibility without the need for frequent recalibration.

• Precision Resistance: 20k Ohm NTC @ 77?F for high-accuracy sensing across commercial heating and cooling ranges.
• Rugged Construction: 6-inch duct mount sensor with a metallic handy box enclosure and NEMA 1 rating.
• Wide Operating Range: Performs reliably in extreme temperatures from -40?F up to 250?F.
• Dust Resistant: Solid-state sensing element is not affected by contaminants in the air stream.
• Universal Excel Compatibility: Seamlessly integrates with Excel 10, 50, 80, 100, and 500 series controllers.

Is the Honeywell C7041B2005 identical to the C7041B2005/U?
Yes, the "U" suffix denotes a universally packaged version of the same technical component; they are functionally and physically identical.

Can this sensor be used for water temperature sensing?
No, this specific model (C7041B) is designed for air duct applications. For immersion or water pipe sensing, refer to the C7041D series.

Does this sensor require calibration?
This is a non-linearized sensor; any required offset or calibration is typically handled through the controller software, as the hardware itself does not support field calibration.
