PTC熱敏電阻(半導體感測器)
| Introduction: |
| PTC Thermistors are semi conductor sensors. These have typical characteristics that change their resistance instantly at a specified pre-defined response temperature (NRT). As soon as the surrounding temperature of PTC reaches it's NRT value the body resistance of PTC Thermistor rises sharply from 200 / 250 Ohms to more than 5000 Ohms. The PTC Thermistors are embedded in the overhang location of the motor windings. The NRT value of PTC is selected according to the Insulation Class of the copper windings of motor or transformers. | |
