Temperature Sensors - NTC Thermistors

The ERT-J0EP473FM is an NTC thermistor, which is a type of temperature sensor. A thermistor is a two-terminal solid-state device that consists of semiconductor material, typically combined with some type of metal oxide. The name thermistor is derived from the words thermodynamic resistor, since its electrical resistance is sensitive to temperature. With NTC thermistors, the resistance decreases as the temperature increases.

Some Key Features of ERT-J0EP473FM

• Usable temperature range of -40 to +110°C
• High sensitivity of -2.5%/K
• High resolution at 0.1°C
• High accuracy of ± 2°C
• Compact size for ease of mountability
• High reliability

Application Fields

Temp sensors are used in a wide range of applications, and the ERT-J0EP473FM is particularly suited for use in automated temperature control systems and other industrial applications. It can be used to measure both absolute and relative temperatures. It is also often used in temperature compensation for electronic circuits such as oscillators, or to provide an accurate measurement of changes in temperature over a period of time.

For example, in some applications such as mechanical sensors, the ERT-J0EP473FM thermistor can be used to measure the displacement of a diaphragm, or the relative temperatures of two parts. In other cases, it might be used to monitor the temperature of a liquid or gas during a process. It can also be used in medical applications, such as monitoring a patient\'s temperature.

Working Principle

The working principle of the ERT-J0EP473FM is based on the concept of thermoelectricity. It works on the principle that when two dissimilar materials with mismatched electron levels are connected, a voltage will be generated. This voltage generated is directly proportional to the temperature difference between the two materials. This makes it possible to measure the temperature with the help of this thermoelectric effect. Moreover, the NTC thermistor is constructed with a ceramic material and metal oxide, which makes it ideal for measuring temperature.

The ERT-J0EP473FM is composed of two terminals connected in an arrangement of resistors. When the connector is connected to a power source, a current passes through these resistors, which generates a voltage. The voltage generated is directly proportional to the temperature of the environment. The voltage generated is then used to calculate the absolute temperature, or the relative temperature change, depending on the application.

In addition, the ERT-J0EP473FM is designed to have a high negative coefficient of resistance. This means that the resistance decreases as the temperature increases. This is beneficial in that it allows for high accuracy and resolution when measuring changes in temperature.

Overall, the ERT-J0EP473FM is a reliable and precise temperature sensor designed for industrial applications. It is composed of a ceramic material and metal oxide, and is capable of measuring absolute and relative temperatures. It is constructed with two terminals connected in an arrangement of resistors, and is designed to have a high negative coefficient of resistance. This allows for high accuracy and resolution when measuring changes in temperature.
