Honeywell C7021B2013 10K Ohm NTC Duct Temperature Sensor 12 Inch

The Honeywell C7021B2013 is a high-precision duct temperature sensor designed for HVAC applications requiring accurate temperature monitoring and control. This sensor utilizes a 10K ohm negative temperature coefficient (NTC) thermistor element that provides reliable temperature readings in commercial and residential heating, ventilation, and air conditioning systems.

Key Features:

• 10K ohm NTC thermistor for precise temperature measurement
• 12-inch insertion probe length for proper duct penetration
• Designed for mounting in supply and return air ducts
• Compatible with Honeywell building automation and HVAC control systems
• Rugged construction for long-term reliability in duct environments
• Wide operating temperature range suitable for most HVAC applications

This duct sensor is commonly used with Honeywell thermostats, controllers, and building management systems to monitor air temperature in ductwork. The 12-inch probe length ensures the sensing element reaches the center of the airstream for accurate temperature readings, avoiding false readings from duct walls. The NTC thermistor technology provides excellent accuracy and stability over the sensor's operating range, making it ideal for precise temperature control applications.
