Honeywell 123448 , Inc. 20K ohm NTC Temperature Sensor for Duct Discharge,

20K ohm NTC Temperature Sensor

The Honeywell RTH221B1021FAL 20K ohm NTC Temperature Sensor for Duct Discharge is a temperature sensor that can be used in ducts to detect pressure. The NTC Thermistor has a rectangular epoxy case and is for use with Honeywell's line of duct mounted TDC sensors, as well as the Analog Temperature Sensor (CMP300), and rotary damper actuator (TDA90).

The Honeywell 1.5 inch diameter 1 millistat model 123448 features a 20K ohm NTC thermistor that can measure temperatures ranging between -55°C and 90°C. This type of thermistor is used to control air conditioning and heating systems by heating or cooling the discharge duct depending on the temperature of the return air stream. The multi-fuse model 92223 provides protection for 115/208-230VAC applications.

NTC thermistor used for duct discharge air temperature measurement.

HONEYWELL® NTC Thermistors for Duct Discharge: Kelvin type sensors for temperature monitoring.

Honeywell offers a full line of NTC Temperature Sensors for use in a variety of industries, including Dryers, Curing Ovens, Refrigeration Systems, and Heat Exchangers.

Protects HVAC equipment for residential applications, Inaccurate signal and reversed polarity protection, Agreed upon accuracy: +/- 0.3% FS (0.25C) (-0.31C to -0.18C), Accuracy at 25C ambient temperature: +/- 0.3% FS, Dimensions are 40x60x30mm

This only requires that you wire the temperature sensor to the fan inside of the duct, which then turns it on when the room reaches a preset temperature. It is easy to install and helps regulate your room's temperature so that you can save energy and money.
