KTY81/110,116 Datasheet/PDFTemperature Sensors - PTC Thermistors
A PTC thermistor (PTC stands for positive temperature coefficient) is a semiconductor device that exhibits a large increase in resistance with increasing temperature. The KTY81/110,116 is a type of PTC thermistor which is made from barium titanate. It has several advantages over other types of thermistors: it is non-linear, self-resetting, heat-stable, and fast response. This makes them ideal for temperature monitoring and other applications where reliability and accuracy are important.
KTY81/110,116 Application Field
The KTY81/110,116 PTC thermistor is widely used in a variety of temperature monitoring and control applications. It can be found in many household appliances, such as ovens, water heaters, and air conditioners. It can also be used in automotive and industrial applications, including robotics and automation systems. The KTY81/110,116 can also be used in medical and military devices, including those that require temperature measurement and/or control.
KTY81/110,116 Working Principle
The KTY81/110,116 works on the principle of temperature-dependent electrical resistance. As the temperature of the sensor increases, the resistance of the PTC thermistor also increases. The KTY81/110,116 is made of barium titanate, a ceramic material with unique electrical properties. It exhibits a large positive temperature coefficient (PTC), meaning that its resistance increases significantly with increasing temperature. The resistance of the KTY81/110,116 increases rapidly as the temperature reaches its “trip point,” which can be set to any temperature between −20°C and 200°C.
When used in temperature-sensing applications, the KTY81/110,116 is typically connected to a bias voltage source. A power supply is then connected to the bias voltage input, allowing the circuit to monitor the thermistor’s resistance in real-time and adjust the applied power as the temperature changes. When used in temperature-control applications, the KTY81/110,116 is typically connected to a heating element, allowing the circuit to monitor the thermistor’s resistance and adjust the applied heat as the temperature changes.
Conclusion
The KTY81/110,116 PTC thermistor is a versatile and reliable temperature sensor that can be used in many different applications. It is highly accurate, with a large positive temperature coefficient and a fast response time. Additionally, it is easy to use and requires minimal external components. These features make the KTY81/110,116 an ideal choice for a wide variety of temperature monitoring and control applications.
