Temperature Sensors - NTC Thermistors

NTC thermistors are temperature sensors designed to measure the temperature of a given area or object. The NTC thermistor is an electronic device that measures the resistance of a material when exposed to a temperature change. The NTC thermistor works by sensing the change in temperature and converting it to a resistivity reading. The resistivity reading is then used to measure the temperature of the environment.

ERT-J0EA400J is just one example of an NTC thermistor application. It is used in applications such as industrial-grade temperature measurement, medical imaging, and automotive electronic system applications.

Working Principle

The principle of operation for the ERT-J0EA400J NTC thermistor is to detect temperature change. Most NTC thermistors are made of a semiconductor material. As the temperature changes, the semiconductor material\'s resistance property also changes. The resistance of the material is an indication of temperature. The material\'s resistivity is typically measured in microohm-centimetres (μΩ-cm).

When temperature increases, the NTC thermistor will decrease its electrical resistance. This temperature-induced change in resistivity is directly proportional to the heat energy provided to the material. This is different from temperature measurement using a thermocouple, because thermocouples use the Seebeck effect to measure the thermal energy instead of the material\'s resistivity.

The ERT-J0EA400J thermistor is designed to detect temperature changes within the range of -40°C to 105°C. It has a thermistor element of 10 ohms at 25°C. Furthermore, it also has a low resistance linearity of 5% and a low voltage operation of 12V. The thermistor element is designed to be very durable, being able to withstand shock, vibration, and even extreme temperatures.

The ERT-J0EA400J thermistor also has a fast response time. It has an excellent temperature-response time of 1.5 milliseconds, allowing it to detect changes in temperature quickly. This makes it useful for applications such as medical monitoring and automobile electronics, where fast response times are required.

The ERT-J0EA400J thermistor is also designed for high accuracy. It has excellent temperature precision of ±0.5°C, allowing it to accurately measure temperatures. This is achieved through the use of the thermistor\'s unique temperature sensing and calibrating system. The thermistor is calibrated to a standard temperature before it is sold, ensuring that it has accurate readings.

Furthermore, the ERT-J0EA400J thermistor is designed with a robust structure. Its housing is made of a rugged ABS plastic, making it highly resistant to shock, vibration, and extreme temperatures. It is also designed for long-term use, with a rated lifetime of over 10 years. This ensures that the thermistor will continue to provide accurate readings over a long period of time.

In conclusion, the ERT-J0EA400J NTC thermistor is an excellent choice for a variety of temperature sensing applications. It is designed for high accuracy, fast response time, durability, and robust design. This makes it an ideal choice for industrial, medical, and automotive applications that require accurate temperature measurements.
