Operating temperature and environment of NTC temperature sensor depend on specific performance of its core element and lead wire:

Different NTC thermistor using in the NTC temperature sensors with the following different operating temperature:

Chip or MF52A,MF51E,MF55: temperature resist grade 125℃,actual temperature resist grade 150℃
MF58: temperature resist grade 200℃,actual temperature resist grade 250℃
MF51: temperature resist grade 200℃,actual temperature resist grade 250℃
Special MF51: temperature resist grade 250℃,actual temperature resist grade 300℃
Weldless chip:temperature resist grade 450℃,actual temperature resist grade 500℃

Operating environment

In the environment of high temperature,high humidty and high corrosion,we suggest to use glass sealed type thermistor as the core element.And MF51 type will be the best NTC thermistor in high humidity environment.



Working principle and types of temperature sensors commonly used in automobiles
Temperature is an important parameter reflecting the state of engine thermal load. In order to ensure that the control system can accurately control the working parameters of the engine, it is necessary to monitor the engine coolant temperature, intake temperature and exhaust temperature at any time, so as to correct the control parameters, calculate the mass flow of the intake air from the cylinder, and perform exhaust purification treatment.

The Coolant Temperature Sensor (CTS) is usually called the water temperature sensor, which is installed on the engine coolant outlet pipe. Its function is to detect the temperature of the engine coolant, and convert the temperature signal into an electrical signal and send it to the ECu. ECU corrects the injection time and ignition time according to the temperature signal of the engine, so as to make the engine work in the best condition.
The Intake Air Temperature Sensor (IATS) is installed in the intake pipe, and its function is to detect the temperature of the intake air, and convert the temperature signal into an electrical signal and send it to the ECU. The intake air temperature signal is a correction signal for various control functions. If the intake air temperature sensor signal is interrupted, it will cause difficulty in hot start and increase exhaust gas emissions.
As we all know, air weight is related to intake air temperature and atmospheric (intake) pressure. When the intake air temperature is low, the air density is high, and the weight of the same volume of gas increases; conversely, when the intake temperature increases, the weight of the same volume of gas will decrease. In the fuel injection system using manifold pressure type, vane type, Kalman vortex type, core type air flow sensor, since the air flow measured by the air flow sensor is volume flow, it is necessary to be equipped with intake air temperature sensor and atmosphere Pressure Sensor. The ECU corrects the fuel injection volume according to the engine's intake air temperature and pressure signals, so that the engine can automatically adapt to changes in the external environment temperature (cold, high temperature) and pressure (plateau, plain). When the intake air temperature is low (high air density), the resistance of the thermistor is large, and the signal voltage of the sensor input to the ECU is high, and the ECU controls the injector to increase the fuel injection; on the contrary, when the intake air temperature is high (low air density) ), the thermistor resistance value is small, the signal voltage of the sensor input to the ECU is low, the ECU will control the fuel injector to reduce the fuel injection volume.

There are many types of temperature sensors, commonly used are thermistor type, metal thermal resistance type, wire wound resistance type, transistor type and so on. Thermistors can be divided into positive temperature coefficient (PTC) type thermistors, negative temperature coefficient (Negative Temperature Coefficient, NTC) type thermistors, critical temperature resistance (critical temperature resistor, CTR) and Linear thermistor. Commonly used thermistors include negative temperature coefficient type and positive temperature coefficient type. Automobiles generally use NTC thermistor temperature sensors, such as coolant temperature sensor (CTS), intake air temperature sensor (IATS), exhaust temperature sensor (Ex-haust Air Temperature Sensor, EATS), fuel temperature sensor (FuelTemperature Sensor) , FTs) etc.
