NTC thermistors are temperature sensors that use the change in resistance due to a reaction to temperature changes. The DC95G503WN is an example of an NTC thermistor. It is a metal oxide resistor that features a 0.4 ohm cold resistance, and a 0.3 ohm hot resistance.

Application Field

The DC95G503WN is commonly used in air conditioning units and refrigerators, as well as in other heating and cooling systems. In air conditioning units, it is usually found in the expansion valve, which controls the amount of refrigerant that enters the evaporator. In refrigerators and other cooling systems, the thermistor is placed near the heat exchanger coil and compresses the refrigerant into the evaporator at high temperature. Additionally, the DC95G503WN can be found in medical equipment, cameras, and automotive applications.

Working Principle

The DC95G503WN thermistor works on the basis of its resistance changing with temperature. When the temperature increases, the resistance will decrease; when the temperature decreases, the resistance will increase. The resistance of the thermistor is related to the temperature in a highly non-linear manner which requires measurement techniques such as thermocouples, thermistors, or RTD\'s for accurate reading and control.

When a DC95G503WN thermistor is used in air conditioning and refrigeration applications, it is used to detect excessive temperatures. When the thermistor detects a temperature that exceeds the set threshold, it will activate a circuit that will shut off the compressor and other components to prevent damage. The thermistor is also used to detect an overload condition, and will shut off the compressor when the overload is detected. Additionally, the thermistor can be used to detect the changes in temperature in the heat exchanger within an air conditioning system, and will adjust the amount of refrigerant entering the evaporator accordingly.

The thermistor also has many other uses in medical, automotive, and other industries. In medical applications, it is used to detect a range of conditions including hypothermia, hyperthermia, and other temperature changes. In automotive applications, the thermistor is used to detect abnormal temperatures in the engine and will shut off the engine in order to prevent damage. The thermistor is also used in various other industrial processes to detect extreme temperatures, and will shut down the system in order to prevent damage.

The DC95G503WN is a robust, reliable, and cost-effective temperature sensor. It has a wide range of applications, and is widely used in various industries. Its high accuracy and ability to detect and respond to temperature changes make it an ideal choice for many applications.
