Temperature Sensors - NTC Thermistors are among the most popular temperature sensors used in various scenarios, and B57321V2681K60 is one of them. As part of the NTC thermistor family, this sensor boasts of an excellent accuracy rating of +/- 1% from -40 to 150 Deg Celsius.

NTC thermistors are sensors that depend on a physical phenomenon that describes the relationship between temperature and the electrical resistance of semiconductors detected at the individual terminals. This is known as the Curie-Weiss law. In essence, as the temperature of a sensor increases, the resistance decreases, allowing more current to pass through the application. In order to provide a meaningful signal, this sensor requires the additional element of a series resistor outside of the thermistor.

This sensor has a high sensitivity to small temperature changes, with a wide linear response of resistance providing accurate temperature readings even when external conditions such as pressure, humidity, or current levels are changing. It also offers reliable voltage readings from a few volts to hundreds of volts, allowing for easy integration with many electrical circuits. The device also houses multiple mounting options such as surface mounting, connector mounting, washer mounting, and glass mounting.

B57321V2681K60 is often used in automotive applications such as engine control, transmission control, as well as HVAC systems. This sensor is extremely popular in refrigeration systems where control of the compressor is required, and fan motors, where the temperature readings can be used to maintain an optimal air flow. In medical applications, such as body temperature and heart rate monitors, this device provides highly accurate readings and helps to maintain the desired level of performance.

The working principle of B57321V2681K60 is simple. The thermistor is connected to a series resistor, and each of those components is connected to two terminals. When the temperature changes, the resistance of the thermistor changes as well, and current flows through the connected resistor, which is then converted into a temperature reading. This reading can be seen on a compatible device such as a resistance-to-temperature indicator, an amplifier, or a microcontroller.

This sensor offers excellent accuracy, robust construction, and wide application range, making it an ideal candidate for a variety of temperature measurement applications. Its wide response range, high operating temperature, and robust design also make it suitable for use in extreme conditions. Due to its low cost, and modular construction, this device has become a popular choice in many consumer electronic devices such as computers, air conditioning systems, and ovens.
