Introduction:

KTY82/121,235 temperature sensors, also known as PTC thermistors, are temperature sensing devices designed to monitor the temperature of a given object or space. They are widely used in a variety of industrial, residential and commercial applications for temperature control, safety and security. Because of their small size and low cost, they are also particularly popular in consumer electronics. In this article, we will explore the application field and working principle of KTY82/121,235 temperature sensors.

Application Field:

KTY82/121,235 temperature sensors are designed to monitor and control temperature in a variety of industrials, residential and commercial applications. In industrial settings, their accurate temperature sensing capabilities make them ideal for various temperature control applications such as HVAC systems, motors, transformers and other temperature-sensitive devices. They are also designed to work in potentially hazardous areas, making them ideal for safety and security applications. In residential and commercial settings, small size and low cost of the KTY82/121,235 temperature sensors make them particularly popular for use in consumer electronics. They are often used in temperature-sensitive products such as refrigerators, air conditioners, stoves, toasters, etc. They are also commonly found in thermostats, alarm systems and other home automation systems.

Working Principle:

KTY82/121,235 temperature sensors use a PTC thermistor to measure temperature. A PTC thermistor is a temperature-sensitive resistor composed of a metal core surrounded by ceramic material. As the temperature increases, the resistance of the thermistor increases as well. The KTY82/121,235 temperature sensors use this increase in resistance to measure temperature. The thermistor is connected to an external voltage source, which is then used to measure the temperature. The temperature sensor passes a current through the thermistor and measures the voltage drop. This voltage drop is then used to calculate the temperature.

Conclusion:

KTY82/121,235 temperature sensors are temperature sensing devices designed to monitor and control temperature in industrial, residential and commercial settings. They use PTC thermistors to measure the temperature, which increases its resistance when the temperature rises. The voltage drop across the thermistor is then used to calculate the temperature. As a result, KTY82/121,235 temperature sensors are highly accurate and cost-effective temperature sensing devices.
