Temperature sensors are devices that measure temperatures and convert them into electrical signals that can be read by other devices. NTC thermistors are one type of temperature sensor that is widely used in many applications. The 121-202EAJ-S01 NTC thermistor is an NTC thermistor specifically designed for temperature sensing applications. This article provides an overview of the 121-202EAJ-S01 application field and working principle.
Application Field
The 121-202EAJ-S01 NTC thermistor is designed for temperature sensing in a variety of applications, including air conditioning systems, refrigerators, ovens, medical equipment, and automotive components. It is a low-cost, reliable solution for both commercial and industrial projects. The thermistor’s temperature ranges allow for precise, accurate readings.
The thermistor can be operated within the temperature range of -40°C to +100°C. It has a wide range of application fields, such as measuring temperature for industrial electronics, medical equipment or automotive industry. It is also suitable for a variety of sensor system applications, such as in HVAC systems or in medical instrumentation.
Working Principle
The 121-202EAJ-S01 NTC thermistor is an NTC (Negative Temperature Coefficient) thermistor, which means that the resistance of the thermistor decreases as the temperature rises. This property is crucial for temperature sensing applications, as it allows for precise temperature measurement by an external device. The thermistor internally and externally composed of ceramic material, and its resistance changes with temperature. The resistance decreases as the temperature increases and vice versa.
The thermistor works by sensing temperature changes. It does this by converting the changes in temperature to changes in resistance, which can then be detected by an external device. The thermistor is used in combination with an external voltage source and a current sensing device. The current sensing device, which is connected to the thermistor, measures the change in the voltage applied to the thermistor and the corresponding change in resistance. This voltage and current change can then be used to determine the temperature of the thermistor.
The 121-202EAJ-S01 is an economical, reliable solution for temperature sensing in a variety of applications. Its accurate temperature ranges allow for precise, accurate readings, making it a great choice for commercial and industrial projects. The thermistor’s precision and reliability make it an excellent choice for use in temperature sensing applications.
