Johnson Controls TE-6311V-2 Duct Mount Temperature Sensor Probe 1K Ohm 8"

The Johnson Controls TE-6311V-2 Duct Mount Temperature Sensor Probe is considered essential in determining air temperature in HVAC systems. This sensor probe has an 8"-long probe that goes straight into the air duct. The end of the probe contains a bulb, which is a temperature-dependent resistor. The electrical resistance of the thermistor is a function of the temperature of the air around the probe. This is a 1K Ohm sensor and its resistance is approximately 1,000 ohms at the reference temperature of 70°F. The controllers of the HVAC system then convert this change in resistance into a temperature number that can be read. This probe is useful in probing the air temperature in the ductwork so that the system can regulate comfort level equipment usage and energy usage.
