Temperature Sensors - NTC Thermistors

NTC thermistors are one of the most common types of temperature sensors. They are used to measure temperatures in a wide variety of applications from medical and automotive to industrial and home applications. The 253JG1F is a type of NTC thermistor that is capable of use in extreme temperature environments. It has a temperature range of -40 to 250°C and a resistance change ratio of 0.059-0.017/K (Kelvin).

Application Field

The 253JG1F thermistor is used to monitor temperatures in a variety of fields. It is a popular choice in automotive, medical, thermal control, energy management, and hazardous environment applications. In automotive applications, the thermistor is used for monitoring engine cooling, monitoring under hood temperatures, and monitoring exhaust gas temperatures. In medical applications, the thermistor is used for monitoring body temperatures, blood oxygen levels, and vital signs. In thermal control and energy management applications, the thermistor is used to monitor temperatures in heating, ventilation, and air conditioning (HVAC) systems, refrigeration units, and other temperature-controlled systems.

Working Principle

The 253JG1F thermistor works on the principle of the negative temperature coefficient (NTC). This means that as the temperature increases, the resistance of the thermistor decreases. The thermistor is made up of two dissimilar materials that are connected electrically. As the temperature increases, the two materials expand at different rates, resulting in a change in resistance. By measuring the resistance of the thermistor at different temperatures, it is possible to determine the temperature. The material used in the construction of the 253JG1F thermistor is made from a special alloy to ensure that it operates correctly at a wide range of temperatures.

The 253JG1F thermistor is designed to be used in a variety of different electrical systems. It can be used in one- and two-wire systems, as well as three-wire and four-wire systems. In one- and two-wire systems, the thermistor is connected to the power supply and the thermistor output is measured. In a three- and four-wire system, the thermistor is connected to the power supply and the thermistor output is compared to a reference voltage. By comparing the thermistor and reference voltages, it is possible to determine the temperature.

The 253JG1F thermistor is a reliable and accurate temperature sensor. It is capable of monitoring temperatures over a wide range of applications and environments. Its resistance change ratio of 0.059-0.017/K makes it an ideal choice for use in extreme temperature environments. Additionally, its wide range of applications and compatibility with a variety of electrical systems makes it a versatile and flexible choice.
