Temperature Sensors are often used to measure various types of temperature. One type of temperature sensor is the Negative Temperature Coefficient (NTC) Thermistor. NTC thermistors are thermally sensitive resistors whose resistance decreases with an increase in temperature. They have wide applications, particularly in temperature-sensing applications. One example of an NTC thermistor is the B57867S104J140, which is a ceramic resistor available in waterproof form.

The B57867S104J140 has a temperature coefficient of -3.9, meaning that it has a resistance decrease of 3.9 ohms°C over a range of 35°C. This decline in resistance results in an increased current flow, which can then be measured with an appropriate meter. The constant temperature coefficient of the B57867S104J140 allows it to display accurate readings over a range of temperatures. This range extends from -50 to 150°C within a tolerance of +/-3°C.

These thermistors are often used in industrial temperature and process control applications because of their reliability and accuracy. They can be used in the monitoring and regulation of various temperatures, such as the temperature of a hot water tank, a steam line, or a refrigerant line. They can also be used to protect electric and electronic components from overheating, by providing readings that will trigger an overtemperature relay or alarm.

The working principle of a B57867S104J140 NTC Thermistor is to generate an electrical voltage, current, or resistance that is proportional to the temperature to which it is exposed. It works by the physics principle that resistance in certain materials, when heated, decreases exponentially. As a result, when the thermistor is heated, its resistance goes down and more current passes through. This change in resistance is then translated into a voltage or current, which can be measured and used to determine the temperature.

The B57867S104J140 also have a low self-heating, which makes them suitable for use in fast response, high accuracy, and low temperature range sensing applications. They also feature a high overload voltage and short-circuit protection, providing enhanced safety for the application. The thermistors are also resistant to vibrations, dust, and humidity, so as to provide long lasting results.

In conclusion, the B57867S104J140 NTC Thermistors are a reliable and accurate temperature-sensing device. They can be used in a wide variety of temperature-sensing applications, providing reliable readings over a wide range of temperatures. With a low self-heating and features such as overload voltage protection and resistance to dust, humidity, and vibrations, the B57867S104J140 thermistors provide long-lasting results for any application.
