B57411V2470K62

Temperature sensors are widely used in modern applications with a variety of industrial and consumer-oriented purposes. They are also used in various human safety-related industries and their functioning is critical for a wide range of operations. One type of temperature sensor is the negative temperature coefficient (NTC) thermistor. The B57411V2470K62 is an example of this type of sensor.

NTC thermistors are a type of thermistor whose resistivity decreases with an increase in temperature. They are made from sintered semiconducting polycrystalline ceramic materials and feature a wide range of temperature sensitivity, ranging from –120°C to 400°C. The B57411V2470K62 is specifically capable of detecting temperatures up to 260°C.

Applications

The range of potential application for NTC thermistors is extremely wide. Common thermistor applications include temperature measurements and control systems for: heating and boiler systems, automotive systems and airbags, air conditioning and climate control, white goods, computer and electronic monitoring systems, laboratory and medical equipment, and other consumer electronics.

The B57411V2470K62 is specifically designed for automotive applications including thermostats, Lambda oxygen sensors, and CMOS control units.

Working principle

NTC thermistors connect the junction between a metal element and a semiconductor via an oxidation process. This joint is embedded in ceramic material and then fired, which produces an NTC thermistor. As the temperature changes, the resistance of the thermistor also changes. Each type of thermistor has a temperature coefficient, expressed as the number of ohms per degree Celsius, or R/°C. This coefficient allows for the thermistor’s resistance to be calculated for any given temperature.

The B57411V2470K62 thermistor is designed to provide the highest possible accuracy and reliability. It offers an extremely tight composite tolerance (±0.3°C), making it particularly suitable for automotive applications. It is also very resistant to changes in temperature and is unaffected by humidity, chemicals, or voltage.

In summary, the B57411V2470K62 thermistor provides accurate temperature sensing in a variety of applications. Its compact design, combined with its composite tolerance, make this type of thermistor a great choice for many purposes.
