Johnson Controls TE-631AM-2 Temperature Sensor

The Johnson Controls TE-631AM-2 is a professional-grade 1k ohm nickel RTD sensor designed specifically for precision temperature monitoring in hydronic HVAC systems and industrial Building Automation Systems (BAS). Featuring a 6-inch stainless steel probe, this well mount temperature sensor delivers high-accuracy readings with a reference resistance of 1000 ohms at 70?F. Built for durability in demanding environments, the TE-631AM-2 includes a rugged galvanized metal enclosure that meets UL 1995 plenum rating requirements for safe installation in ceiling spaces and air handling units.

For veteran contractors, the TE-631AM-2 simplifies field installations by providing a complete well insertion temperature sensor assembly in a single box. The unit operates effectively across a broad temperature range of -50? to 220?F, ensuring reliable performance in both heating and cooling applications. The TE-6300 series architecture allows for easy maintenance with a replaceable sensing probe, while the 22 AWG lead wires facilitate a standard two-wire connection to most Johnson Controls and third-party controllers. This nickel temperature element is the technician's choice for long-term stability and resistance to corrosion in thermal well applications.

• Corrosion Resistance: The 6" stainless steel probe and galvanized enclosure provide superior protection against harsh hydronic environments.
• Plenum Rated: Meets UL 1995 standards, allowing for versatile mounting in plenum spaces without additional shielding.
• Direct Controller Compatibility: Standard 1k ohm nickel resistance curve integrates seamlessly with Metasys and other major BAS platforms.
• Installation Efficiency: Includes a 0.88-inch hole for 1/2-inch conduit fittings, reducing time spent on field modifications.

• Can this be mounted without a thermal well? While designed as a well mount sensor, it is primarily intended for use with TE-6300W series thermal wells (sold separately) to maintain a sealed system in liquid applications.
• What is the wiring limit for this nickel sensor? To minimize signal error, it is recommended to limit field wiring resistance to 3 ohms or less; typically 100 feet for 22 AWG or 250 feet for 18 AWG.
• What size conduit fitting does the enclosure support? The metal cover kit features an 0.88-inch hole designed for standard 1/2-inch NPT conduit fittings.
