Description
The Honeywell C7021J2007 is a 12′ duct temperature sensor suitable for HVAC systems. It uses an NTC thermistor of Type II with a reference resistance of 10k Ohm at the reference temperature. This sensor is used to calculate the average temperature of air moving within a duct, by taking the average of temperatures at various points along the duct. This averaging capability gives a better temperature measurement than the single-point sensor, which in turn gives better control of the system and power usage. The C7021J2007 applies to different types of HVAC system equipment such as air handling units, chillers and fan coil units.
