Temperature sensors are tools used to measure temperature through the heating and cooling of objects. These sensors come in various shapes and sizes and can measure temperatures from extreme high to extreme low ends. The B57891M0105K000 sensor is an NTC Thermistor that is used to measure temperatures in a variety of applications.

An NTC thermistor is a Negative Temperature Coefficient thermistor, meaning that its resistance decreases with an increase in temperature. This type of thermistor is made from a metal oxide semiconductor material which is activated with a gas or solution and then sealed. The outer layer is usually made of ceramic, metal, or plastic and is then connected to leads. When voltage is applied to the thermistor, current passes through it. The electrical resistance of the thermistor then varies depending on the temperature, and this is then used to estimate the temperature of the environment.

The B57891M0105K000 NTC Thermistor is primarily used in automotive and industrial applications. In cars, it is used to measure the temperature of oil and coolant, and is part of sensors such as the MAP sensor, MAF sensor, and EGR valve. In industry, the sensor is employed for process monitoring and data logging, as well as industrial heating and cooling. It can also be used as a temperature monitoring control in electro-mechanical systems.

As for its working principle, when a voltage is applied to the thermistor, the current is monitored at a fixed rate; this current decreases with an increase in temperature. As the current is monitored, it changes proportionally to the temperature. Eventually, the electrical resistance can be used as an indication of the temperature.

The B57891M0105K000 NTC Thermistor is a reliable and cost-effective temperature sensor that is used in automotive and industrial applications. It works on the principle of Negative Temperature Coefficient and employs a circuit to monitor and regulate the current at a fixed rate to measure the resistance as the temperature changes. This makes it an ideal solution for accurate temperature monitoring in a variety of settings.
