Honeywell C7021R2000 , Inc. 10K ohm NTC Type II Averaging Temperature Sensor,12ft, Operating range -40-250F

12' DUCT AVG FLEXIBLE COPPER

The Honeywell C7021R2000 is a single wire 12' DUCT AVG FLEXIBLE COPPER temperature sensor used for indicating temperature, and sensing over a small range of temperatures. It provides a resistance output suitable for driving an analog relay or the like. The end terminal is connected to one side of the thermistor body that forms a part of the thermoelectric couple to sense the temperature. The other side of the thermistor body provides the corresponding electrical resistance characteristic curve for use in calibrating a controller, meter, or display instrument.

DUCT MINIATURE THREADED SENSOR, PLUG IN WALL MOUNT, -40'F TO 250'F, NEMA 4X

The C7021R2000 mounts 12 feet from the surface of the air supply.This sensor is for most heating and cooling appliances including forced air furnaces, baseboard electric heaters, radiators, oil fired central furnaces, water & steam boilers and fan-forced heaters. This sensor also works with many other types of heating and cooling equipment such as: radiant flooring, fan coil units, hydronic radiant systems, unit ventilators swamp coolers, and window air conditioners.

The C7021R2000 flexible NTC is a 12 ft version of the standard 6 ft Averaging NTC devices with a typical resistance range of 10K - 12.5K

NTC Flexible Resistor cable constructed of a flexible copper clad litz wire in a fluoropolymer jacket. The materials used in this cable like NTC Thermistors are specified for accuracy and stable resistance. The flexible copper clad litz wire is wrapped around the Thermistor element which is housed in PVC jacket to protect it from damage during installation.

This wire is rated for use in air handling & ventilation applications, but may also be used for other temperature sensing applications.

The C7021R2K0 temperature sensor from Honeywell offers a 2-wire type with 12' of cable to meet nearly any temperature sensing application. The flexible cable is designed for use in HVAC applications such as residential and commercial air conditioning heating, self-contained units and window air conditioners.
