Temperature Sensors - NTC Thermistors

NTC thermistors are temperature-sensing electronic components which are widely used for temperature sensing in many applications. NTCLE300E3502SB is an NTC thermistor commonly used in many electronics and instrumentation applications. It is generally used in a bridge circuit with two equal resistors as one of the arms, or in a 3-terminal system with two equal resistors in series.

Typical application field

The NTCLE300E3502SB thermistor offers great advantages when used in temperature sensing applications. It is used in various applications such as automotive, medical devices, HVAC & refrigeration, consumer electronics, and more. It is also used to measure temperature in laboratory equipment, printed circuit boards, and process control equipment. The NTCLE300e3502SB can also be used in industrial applications such as controlling motors and pumps, providing over-temperature protection, and preventing other failure conditions. It can also be used in automotive applications such as engine control and interior temperature monitoring.

Working principle

NTC thermistors work on the principle of thermal inertia. As the temperature of the device increases, the resistance of the thermistor decreases. This property makes them suitable for measuring temperature changes. The NTCLE300E3502SB is a linear thermistor, which means that the resistance of the thermistor changes linearly with the temperature of the device.The NTCLE300E3502SB thermistor is typically used in a two-resistor bridge circuit, in which the thermistor is connected to two resistors of equal resistance. When the temperature of the device is lower than the set point, current flows through the thermistor from the higher reference voltage and the higher reference voltage is nominated as the set point. When the temperature of the device increases, the resistance of the thermistor decreases, resulting in a decrease in the current flowing from the higher reference voltage to the lower reference voltage. The lower reference voltage is then nominated as the set point.The NTCLE300E3502SB can also be used in closed loop systems, where the temperature reading is compared with a pre-set temperature. If the temperature is higher than the pre-set temperature, the device will activate a cooling system or an alarm. If the temperature is lower than the pre-set temperature, the device will turn off the cooling system or an alarm.

Conclusion

The NTCLE300E3502SB thermistor is a widely used temperature sensor that is suitable for many applications. It is easy to connect in a bridge circuit with two resistors of equal resistance, or in a three-terminal system with two resistors in series. It has the advantage of linear temperature sensitivity, making it suitable for applications such as engine control, process control, and over-temperature protection.
