TE-702-C-17-A | 20K Ohm | Duct Temperature Sensor | Sensor Length: 4 inch | NEMA 4 Housing | MAMAC Systems

**4" 20K Ohm NTC Duct Temp Sens by MAMAC Systems** The MAMAC Systems TE-702-C-17-A is a 4-inch NTC (Negative Temperature Coefficient) duct temperature sensor with a resistance of 20K ohms. It is used to measure the temperature of air or gas flowing through a duct. The sensor is made of a semiconductor material that changes resistance in response to changes in temperature. The higher the temperature, the lower the resistance. This change in resistance can be measured by a temperature controller or other device to provide an accurate reading of the temperature of the air or gas flowing through the duct. **Features:** * 4-inch diameter * 20K ohms resistance * NTC (Negative Temperature Coefficient) * Measures temperature of air or gas flowing through a duct * Made of a semiconductor material that changes resistance in response to changes in temperature * The higher the temperature, the lower the resistance * This change in resistance can be measured by a temperature controller or other device to provide an accurate reading of the temperature of the air or gas flowing through the duct **Benefits:** * Accurate temperature measurement of air or gas flowing through a duct * Can be used in a variety of applications, including HVAC, industrial, and commercial * Durable and reliable Shop now at our HVAC supply store for the best prices and fast shipping on the MAMAC Systems TE-702-C-17-A 4" 20K Ohm NTC Duct Temp Sens!
