Johnson Controls TE-631AM-1 Temperature Sensor

The Johnson Controls TE-631AM-1 is a high-precision 1000 Ohm Nickel RTD immersion temperature sensor engineered for professional HVAC and building automation systems (BAS). Featuring a 6-inch stainless steel probe, this sensor delivers highly accurate and stable temperature feedback in hydronic applications. The TE-6300 series design includes a rugged, corrosion-protected steel enclosure that meets UL 1995 plenum requirements, making it ideal for commercial mechanical rooms. With a wide operating range of -50 to 220 degrees Fahrenheit, the TE-631AM-1 ensures dependable performance across extreme thermal cycles. This model comes equipped with a 1/2-14 NPT threaded well sensor holder and a brass threadless well adapter, facilitating straightforward retrofits into existing TE-6300W-103 or WZ-1000-5 thermowells. For technicians specializing in Johnson Controls Metasys or Facility Explorer environments, this nickel temperature sensor serves as a reliable direct-replacement component for maintaining system setpoints and discharge water accuracy.

• High-Stability 1k Ohm Nickel Element: Provides a sensitivity of approximately 3 Ohms per degree Fahrenheit for precise HVAC temperature control.
• Durable Construction: Features a stainless steel insertion probe and galvanized steel enclosure to resist moisture and industrial contaminants.
• Plenum Rated: The metallic housing ensures compliance with fire and safety standards for installation in air handling spaces.
• Retrofit Compatibility: Includes the TE-6300-612 adapter, allowing for easy installation into legacy thermowells without system draining.

What is the resistance at 70?F for this sensor?
The TE-631AM-1 uses a 1k ohm nickel element calibrated to 1000 ohms at 70?F (21?C).

Can this sensor be used in duct applications?
While primary for well-insertion or immersion, the TE-6300 series offers specific duct models; however, this immersion unit is designed specifically for liquid sensing in thermowells.

Is the thermowell included with this part?
No, the TE-631AM-1 includes the sensor, enclosure, and retrofit adapter. The TE-6300W series thermowell must be ordered separately if a new one is required.
