High Accuracy Ring NTC Thermistor 6mm For Vehicles Yachts Ship Meters Water Temperature Sensors
Description Of The Ring NTC Thermistor
Negative temperature coefficient (NTC) thermistors are among the most common devices used to monitor ECU temperatures. The NTC is a passive resistor, and the resistance of an NTC varies with temperature. More specifically, as the ambient temperature around an NTC increases, the resistance of the NTC decreases.The coolant temperature sensor has a built-in NTC resistor. The resistance of a Negative Temperature Coefficient (NTC) resistor decreases when the temperature increases. The resistor in the sensor together with a resistor in the ECU forms a voltage divider which is fed by a 5 V power supply.
Features Of The Ring NTC Thermistor

Application Of The Ring NTC Thermistor
* Automotive electronics
* Measurement of cooling water and
* Measurement of oil temperature
What advantage does a thermocouple have over the NTC thermistor?
The thermocouple has high accuracy as compared to the thermistor.
The thermistor has lead whose resistance reduces their accuracy.
The temperature measuring ranges of the thermistor is -50°C to
250°C whereas that of the thermocouple is -200°C to 1250°C.
