Johnson Controls TE-631AM-2 Well Mount Temperature Sensor
The Johnson Controls TE-631AM-2 is a well mount temperature sensor engineered for accurate and reliable fluid temperature measurement in hydronic heating, cooling, and building automation systems. Designed for insertion into an immersion well or thermowell, this sensor keeps the sensing element in direct thermal contact with the pipe fluid without requiring system shutdown for removal or replacement — an essential advantage in commercial and industrial HVAC applications.
Key Features
- Well mount design for easy installation and serviceability without draining the system
- 6-inch probe length for adequate immersion depth in standard pipe sizes
- Nickel sensing element for excellent accuracy, repeatability, and long-term stability
- 1,000 Ohm (1K Ohm) resistance output for compatibility with a wide range of building automation and DDC controllers
- Designed for use with Johnson Controls and compatible BAS/DDC control systems
- Rugged construction suitable for commercial HVAC and hydronic piping applications
Typical Applications
- Hydronic heating and cooling supply/return temperature monitoring
- Chilled water and hot water loop sensing
- Building automation system (BAS) and direct digital control (DDC) integration
- Boiler and chiller plant temperature measurement
- Commercial HVAC piping systems requiring well-mounted sensing
