B57891M0123J000 Temperature Sensor - NTC Thermistors

A temperature sensor is a device that detects and measures temperature in order to provide feedback for controlling a system. The B57891M0123J000 temperature sensor is a negative temperature coefficient (NTC) thermistor, meaning that it has a resistance that decreases as its temperature increases.

Application Field

NTC thermistors, such as the B57891M0123J000, are commonly used in a wide variety of applications, including automotive, industrial, and medical. In automotive applications, they are typically used for cooling systems, HVAC systems, and engine management systems. In industrial applications, NTC thermistors are commonly used in process monitoring and control, environmental monitoring, and power control. In medical applications, NTC thermistors are often used to measure body temperature, and in drug delivery devices, and x-ray machines.

Working Principle

The B57891M0123J000 works by measuring the resistance of an NTC thermistor. NTC thermistors work by having a resistance that changes inversely with temperature. This means that as the temperature increases, the resistance decreases. The B57891M0123J000 works by measuring this resistance with a precise, high-resolution analog-to-digital converter. The voltage output of the A/D converter is then converted to a temperature value using the NTC thermistor’s temperature-resistance characteristic curve.

Summary

The B57891M0123J000 temperature sensor is a Negative Temperature Coefficient (NTC) thermistor that is commonly used in automotive, industrial, and medical applications. It works by measuring the resistance of an NTC thermistor, which has a resistance that decreases as its temperature increases. The resistance is then converted to a temperature value using the thermistor’s temperature-resistance characteristic curve.
