Johnson Controls TE-631GV-2 Temperature Sensor

As a veteran tech, you know that consistent signal reliability is the backbone of any building automation system. The Johnson Controls TE-631GV-2 is a high-precision 1k ohm nickel temperature sensor designed for critical VAV flange mount applications. This unit serves as the direct replacement for TE-631GV-1, ensuring a seamless swap-out without the need for recalibrating your controller's input curves. Featuring a 4-inch stainless steel insertion probe, this sensor provides superior resistance to corrosion and physical wear within the airstream, delivering an accurate resistance output even in demanding environments.

The TE-631GV-2 is engineered for duct temperature monitoring with a sensitivity of approximately 3 ohms per degree Fahrenheit. Its flange mount design includes a metallic enclosure that meets UL 1995 plenum use requirements, making it a go-to for contractors working in schools, hospitals, and commercial high-rises. With a wide operating range of -50°F to 220°F, this HVAC duct sensor handles everything from standard air handling unit discharge to extreme return air conditions. The package includes 10 feet of plenum-rated cable with quick-connect terminations, significantly reducing commissioning time on the job site.

• Precise 1k Ohm Nickel Element: Delivers stable, long-term accuracy with a proven resistance/temperature response curve for BAS compatibility.
• Durable 4-Inch Stainless Probe: The corrosion-resistant 0.25" diameter probe is built to withstand high-velocity airflow and moisture.
• Plenum Rated Construction: Includes a metallic enclosure and 10 ft plenum cable, ensuring compliance with strict fire and safety codes.
• Easy Installation: The flange mount provides a secure, vibration-resistant fit with two included self-drilling screws.
• Direct Replacement: Specifically updated to replace the discontinued TE-631GV-1, keeping your legacy systems running without modification.

Is the TE-631GV-2 compatible with non-Johnson Controls systems?
Yes, as long as your DDC controller is configured to accept a standard 1k ohm nickel (Balco/Nickel-Iron) RTD input, this sensor will provide accurate data.

Can I use this sensor in an outdoor air application?
While the 4-inch probe is versatile, this specific model is optimized for flange-mount duct or VAV applications. For outdoor air, a dedicated OSA sensor with a protective sun shield is recommended.

What is the wiring configuration for this part?
This is a passive, two-wire resistance output device. It comes with a 10-foot plenum-rated cable featuring 1/4-inch female insulated quick-connect terminations for fast field wiring.
