Temperature Sensors - NTC Thermistors

Temperature Sensors are the key components in various measuring systems. NTC thermistors are temperature-sensitive electrical components used in many applications for environmental monitoring and control of temperature. This article will discuss the application field and working principle of B57621C332K62 thermistors.A thermistor is a temperature-dependent resistor, usually composed of a ceramic material mixed with metal oxides. B57621C332K62 is an NTC thermistor that operates in negative temperature coefficient (NTC) mode. It can be used in a wide range of temperature measuring and controlling applications, such as thermostats, humidity sensors, and automotive air flow sensors.When subjected to a temperature change, the resistance of an NTC thermistor will change proportionally. This feature makes it a perfect temperature sensor because it allows for accurate measurement of temperature changes. In B57621C332K62 thermistors, the resistance decreases as the temperature rises.The B57621C332K62 thermistor is composed of a sintered ceramic disc with two metallic leaded wires soldered to its ends. The lead wires embedded inside the device are made from manganese dioxide and silver pellet. This thermistor is very stable and can be used in temperature measurements in extreme conditions ranging from -40 degrees Celsius to + 150 degrees Celsius.When an electrical voltage is applied to B57621C332K62 thermistors, the device releases heat and its resistance decreases. This is known as self-heating effect. The heat generated by the thermistor results in the resistance of the device decreasing. The greater the voltage, the greater the amount of self-heating in the thermistor will be.The working principle of B57621C332K62 thermistors involves the thermistor responding to changes in temperature by changing its resistance. As the temperature rises, the B57621C332K62 thermistor’s resistance decreases accordingly. This change in resistance can be measured by the external circuit and used to determine the temperature of the environment. The device is also able to detect other environmental changes such as pressure and humidity.In conclusion, B57621C332K62 thermistors are widely used in a variety of applications due to their temperature sensitivity and stability. Temperature sensors have become an indispensable part of device measurement systems. NTC thermistors are an ideal choice for their reliability and precise measurements. They are able to accurately measure and respond to changes in temperature, pressure, and humidity.
