Temperature Sensors - PTC Thermistors

PTC Thermistors are temperature sensors that use a positive temperature coefficient (PTC) to measure temperatures. PTC thermistors are usually made from ceramics, polymers, or semiconductors, that show a significant increase in electrical resistance when exposed to increased temperatures. A PTC thermistor becomes resistive at a certain temperature and its resistance increases as the surrounding temperature rises. The KTY11-5 is a PTC thermistor commonly used for temperature control and sensing applications.

KTY11-5 Application Field

KTY11-5 thermistors are widely used in various applications, including water heaters, heater controllers, temperature control systems, motor speed controls, air conditioners, and refrigerators. They are also used in automotive electronic control systems as well as in consumer appliances. With its compact size and superior sensitivity, the KTY11-5 is well suited for monitoring temperatures in low power circuits.

KTY11-5 Working Principle

The KTY11-5 thermistor works on the principle of increasing resistance with temperature. When the thermistor is exposed to rising temperatures, its resistance increases accordingly. The KTY11-5 is usually connected to a voltage divider circuit in order to measure temperature. A voltage divider is a very simple circuit that helps to sense resistive changes and measure the resistance. The thermistor\'s resistance is measured by connecting it to a voltage source, which generates a proportional voltage across both resistors depending on the thermistor\'s resistance and the voltage applied. The voltage output can then be used to determine the temperature being sensed by the thermistor.

Conclusion

The KTY11-5 is a popular and versatile PTC thermistor that can be used in a variety of temperature monitoring and control applications. Its small size, durability, and superior sensitivity makes it the ideal choice for low-power circuits. Its working principle is based on the fact that its resistance increases as the temperature increases, allowing for accurate temperature sensing and control.
