Johnson Controls TE-631AP-1 Temperature Sensor

The Johnson Controls TE-631AP-1 Temperature Sensor is a professional-grade 1000 Ohm Nickel RTD specifically engineered for precision monitoring in HVAC building automation systems. This immersion temperature sensor features a 6-inch stainless steel probe and a threadless sensor holder, making it an ideal choice for well-insertion applications where thermal response and long-term stability are critical. Encased in a rigid thermoplastic NEMA 1 rated conduit box, the unit provides reliable performance across a broad operating range of -50 to 220 degrees Fahrenheit. As part of the TE-6300 series, this nickel temperature sensor utilizes a high-accuracy 1k ohm @ 70?F element, ensuring seamless integration with standard North American controllers. The inclusion of a 1/2-14 NPT female thread simplifies conduit connections, while the replaceable probe design reduces maintenance overhead for field technicians. For contractors managing large air handling units or hydronic loops, this precision HVAC sensor offers the durability needed for demanding mechanical room environments without unnecessary complexity.

• High Stability Sensing: The 1k ohm nickel active element minimizes drift over time, reducing the need for frequent recalibration.
• Durable Enclosure: The noncorrosive thermoplastic conduit box protects internal wiring from environmental contaminants.
• Installation Efficiency: Features a 1/2-14 NPT threaded hub and a threadless sensor holder for rapid mounting in thermal wells.
• Broad Compatibility: Standard resistance output works natively with most Johnson Controls and third-party BAS platforms.
• Corrosion Resistance: The 6" stainless steel probe ensures longevity when submerged in immersion wells or exposed to high-humidity airflows.

What is the accuracy of the TE-631AP-1?
This model provides a standard accuracy of ? 0.34?F (? 0.19?C) at reference temperatures, ensuring high-fidelity data for energy-efficient sequencing.

While designed for well-insertion, the 6-inch probe can be used in duct applications; however, for direct fluid immersion, a compatible thermal well is required to protect the probe and prevent leaks.

For this 1k ohm nickel sensor, keep total wire resistance below 3 ohms. Using 18 AWG wire, you can typically run up to 250 feet before experiencing a 1?F error.
