Thermistor is a temperature measurement sensor that utilizes the property of a material's resistance changing with temperature to measure temperature. Compared with other temperature sensors such as thermocouples, thermistor provides excellent accuracy, stability, and repeatability, especially suitable for measurement in the medium and low temperature range. The core part of a thermistor is a BTA16-800BWRG resistor made of pure metal or metal alloys such as platinum, copper, or nickel. The resistance value of these materials varies with temperature, making thermistor an ideal choice for accurate temperature measurement.diode
The main types of thermal resistors are platinum resistors and copper resistors. Among them, platinum resistors are widely used due to their high precision, good stability, and wide temperature range (-200 ℃ to 850 ℃). Copper resistors, due to their lower cost, can also meet general measurement needs within a smaller temperature range.diode
The working principle of thermal resistance
The working principle of a thermal resistor is based on the characteristic of its resistance changing with temperature. For most metals, resistance increases with temperature. The relationship between the resistance of a thermal resistor and temperature can be expressed by the following equation:diode
