Temperature Sensors - NTC Thermistors: 197-302LAG-A01 Application Field and Working Principle

NTC thermistors are temperature sensors commonly found in industrial operations, and the 197-302LAG-A01 is no exception. NTC thermistors are semiconductor devices that have resistance that varies depending on temperature. They are made with a conductive oxide material, such as MnO2, which forms a semiconductor structure similar to an MOSFET.

Application Field

The 197-302LAG-A01 NTC thermistor is designed primarily for temperature measurement and control, and are used in a variety of applications due to their wide temperature range and high accuracy. This thermistor can be found in applications ranging from industrial machinery, HVAC/R systems, and medical equipment to aircraft and automotive systems. It is also often used in smart home appliances and energy-saving thermostats.

Working Principle

NTC thermistors such as the 197-302LAG-A01 are resistor-capacitor devices that rely on the thermoconductivity of the material in order to measure and regulate temperature. The device works by measuring the instantaneous voltage across a resistor which is proportional to the temperature, and is then regulated by changing the resistance of the material in order to maintain the desired temperature.Under normal conditions, the thermistor behaves like a regular resistor, meaning that its resistance increases as temperature increases. When temperature changes, the resistance in the material changes, leading to a change in the voltage across the thermistor. This change in voltage is then used to regulate the temperature of the system.When the 197-302LAG-A01 is used in conjunction with temperature controllers, it can be used to regulate the temperature of an environment. The temperature controller measures the temperature output of the thermistor and regulates the temperature of the system accordingly.

Conclusion

The 197-302LAG-A01 NTC thermistor is a highly accurate and reliable temperature sensor. It is used in a variety of applications, including industrial machinery, HVAC/R systems, medical equipment, aircraft, automotive, and smart home appliances. Its working principle is based on the thermoconductivity of the material, and it is regulated by changing the resistance in response to changes in temperature.
