Honeywell C7031D2003 Temperature Sensor

The Honeywell C7031D2003 is a professional-grade immersion temperature sensor designed for high-accuracy monitoring in commercial hot and chilled water systems. Engineered for seamless integration with DDC systems and the Honeywell Excel series, this PT1000 electronic sensor features a 1097-ohm resistance at 77?F, ensuring stable signal transmission for critical HVAC control applications. The 5-inch stainless steel probe is built to withstand demanding hydronic environments, providing a broad operating range from -40?F to 350?F. As a direct replacement for the C7031D2003/U, this unit offers veteran technicians a reliable solution for aquastat or standalone temperature sensing without the need for field calibration. The solid-state design is highly resistant to dust and moisture, maintaining precise RTD sensing accuracy even in fluctuating thermal conditions.

Key Benefits:

• High-Precision Monitoring: Utilizes a PT1000 element with a 1097-ohm reference for pinpoint accuracy in hydronic loop management.
• Versatile Application: Optimized for both chilled water sensors and high-temp hot water tracking, spanning -40?F to 350?F.
• Seamless Integration: Fully compatible with Honeywell T775 standalone controllers and Excel 500 series DDC platforms.
• Industrial Durability: Features a corrosion-resistant 5-inch immersion mounting probe suitable for high-pressure water environments.
• Plug-and-Play Maintenance: Solid-state components ensure long-term stability and zero drift for consistent building automation performance.

Common Questions:

• What is the difference between the C7031D2003 and the C7031D2003/U? These units are technically identical; the "/U" suffix simply denotes the universal retail packaging version.
• Does this sensor require a separate immersion well? Yes, for standardized hot or chilled water piping, a machined well (such as the 50001774-001) is typically paired with this 5-inch probe for optimal heat transfer.
• Is this compatible with 20k Ohm NTC systems? No, this is a PT1000 platinum-based sensor. Ensure your controller is configured for 1097-ohm PTC inputs to avoid scaling errors.
