Temperature sensors are devices that measure temperature or temperature gradient by sensing heat. These temperature detectors include thermocouples, semiconductor, thermistors, thermograph, and PTC thermistors. PTC thermistors are particular types of thermistors that have Positive Temperature Coefficient and are used in a wide range of applications.

KTY81/121,112 is a family of NTC thermistors (NTC stands for Negative Temperature Coefficient). These thermistors use the resistance changing property of ceramics to measure temperatures. KTY81/121,112 thermistors are encapsulated with an insulating epoxy probe. and have excellent corrosion and vibration resistance.

Due to their ability to quickly and accurately measure temperatures, KTY81/121,112 are popular in a variety of application areas. The most common areas of application are industrial automation, automotive, process control, HVAC systems, and consumer electronics. Here are just some of the most widely used applications:

• Monitoring electricity flow in power-monitoring devices
• Measuring air temperature in water heaters and air conditioners
• Detecting motor overloads
• Measuring temperatures of artificial organs
• Measuring temperatures of electrical transformers
• Measuring winding temperature in rotors
• Detecting open or short circuits in electrical equipment
• Regulating fans and motors
• Measuring and controlling temperatures in food and clothes dryers

The working principle of KTY81/121,112 thermistors is that they detect the various temperature changes in their environment and use their resistance to send a signal to a measuring instrument, which then presents these readings in the form of an electrical signal. This electrical signal then used to measure the temperature at the location where the thermistor is installed. When the PTC thermistors are exposed to temperatures lower than the specified room temperature, their resistance increases, while exposure to higher temperatures will decrease their resistance. This process provides an accurate measurement of temperature.

The versatility of KTY81/121,112 thermistors makes them ideal for temperature sensing in a wide range of industries and applications. Whether it’s used in motor overload detection, foods dryers, artificial organs, or HVAC systems, KTY81/121,112 thermistors provide reliable temperature readings and protection in various environments.
