Johnson Controls TE-635AP-1 Temperature Sensor

The Johnson Controls TE-635AP-1 is a professional-grade platinum temperature sensor designed for accurate thermal monitoring in heavy-duty HVAC systems. Featuring a 6-inch probe length and a 1k ohm platinum RTD (Resistance Temperature Detector) element, this unit delivers high-precision signal output compatible with most modern building automation systems (BAS). As the official replacement for the legacy TE-632AP-1 temperature sensor, it integrates a simplified well-insertion design that slides directly into standard thermowells. The inclusion of a thermoplastic conduit box with a 1/2-14 NPT female thread ensures a secure, code-compliant electrical connection for field wiring. Built for durability, the stainless steel probe resists corrosion while maintaining a rapid thermal response time in both liquid and air applications. Whether you are performing a replacement temperature sensor swap or a new installation, this Johnson Controls sensor provides the reliability required for commercial climate control loops.

Key Benefits:

• Direct Retrofit Compatibility: Functions as the primary update for the TE-632AP-1, ensuring seamless mechanical and electrical fitting.
• High-Accuracy Platinum Element: The 1k ohm platinum RTD sensing technology offers superior stability and lower drift than standard thermistors.
• Rugged Conduit Integration: Ships with a durable enclosure and conduit adaptor to protect internal terminations from environmental debris.
• Precision Well Mounting: The 6-inch probe is optimized for immersion applications, providing accurate core temperature readings in piping and ductwork.

Common Questions:

• Is the TE-635AP-1 compatible with my existing TE-632AP-1 setup? Yes, this model is the designated updated version and maintains the same 1k ohm platinum curve and 6-inch form factor.
• Does it include the mounting enclosure? Yes, this package includes the integrated conduit box and sensor holder for immediate installation.
• Can this be used for air duct sensing? While primary for well-insertion, it can be adapted for duct applications using a standard mounting flange.
