Johnson Controls TE-631JM-1 Duct Temperature Sensor 1000 Ohm 18 Inch Probe

The Johnson Controls TE-631JM-1 is a duct-mounted temperature sensor designed for HVAC applications requiring precise air temperature monitoring. This sensor features an 18-inch insertion probe that extends into ductwork to accurately measure air temperature in commercial and industrial heating, ventilation, and air conditioning systems.

Key Features:

• 1000 Ohm (1kΩ) thermistor sensor element for accurate temperature measurement
• 18-inch probe length ideal for large duct applications and center-of-duct sensing
• Duct-mount configuration designed for direct insertion into HVAC ductwork
• Compatible with Johnson Controls building automation and HVAC control systems
• Rugged construction suitable for commercial HVAC environments

This temperature sensor is commonly used in commercial building automation systems, air handling units, and central HVAC systems where accurate duct air temperature monitoring is critical for proper system operation and energy efficiency. The 1kΩ thermistor provides reliable temperature sensing for control and monitoring applications.
