KTY82/110,215 Sensors, Transducers

Temperature Sensors - PTC Thermistors are a type of heat-sensitive semiconductor that vary in resistance when exposed to different temperatures. The KTY82/110,215 is a such device widely used in applications in which a low-profile, low-resistance temperature sensor is desired.

This type of thermistor is a two-lead device that is composed of a semiconductor material doped with a special type of electrically conducting material, called a dopant. The currents flowing through the device are proportional to the temperature of the device. The device can be powered from a power supply or from a voltage source, such as an AC voltage.

The primary application of the KTY82/110,215 is in the measurement of temperature. It is an ideal device for use in applications such as automotive, medical, or HVAC systems. It is also used in other applications, such as in LEDs for light dimming control. Due to its low resistance values, it is also often used in power supplies, such as solar power supplies.

The working principle of the KTY82/110,215 is based on the beneficial property of semiconductors, namely their ability to exhibit a significant change in resistance when exposed to electrical current. This is termed the positive temperature coefficient (PTC) effect. As the temperature rises, the PTC material increases its resistance, while as the temperature decreases, the PTC material decreases its resistance.

This PTC effect is due to the fact that as temperature increases, the resistance of the device increases. This change in resistance is then used to measure a temperature change. The device is typically powered through a voltage source, such as an AC voltage, and the output is then allowed to pass through a variety of measuring devices, such as thermometers, range finders, etc.

The KTY82/110,215 thermistors are available in a variety of packages and can also be obtained in multiple temperature ranges. With its low resistance values, and its low profile, this device is perfect for applications in which a temperature sensing solution is desired.
