Temperature sensors are designed to measure the temperature of a system or an environment and are essential in many industrial applications, particularly those that require safety protocols due to their sensitivity. The PTC (Positive Temperature Coefficient) thermistor is one such temperature sensor used for measuring temperatures ranging from below 0°C to 200°C. The KTY81/122,112 is one particular type of PTC thermistor that has a wide range of applications.

Applications of KTY81/122,112

The KTY81/122,112 can be used as a temperature switch and is suitable for many different temperature monitoring and switch-off applications. It is suitable for use in automotive applications, industrial machines, heating systems, power supplies and is even suited to medical and communications systems with its high temperature accuracy. What makes this thermistor so suitable for these applications is its high resistance in the cold state, and its low resistance in the hot state.

The KTY81/122,112 can also be used as a temperature measurement and control sensor. This thermistor is widely used in systems such as temperature controllers, temperature controllers for ovens, or even automated heating and cooling systems. It is not only used as a temperature control element, but also as a temperature measurement element, such as in temperature gauging systems. Due to its ability to work accurately at a wide range of temperatures, it is suitable for these systems.

Working Principle of KTY81/122,112

The working principle of the KTY81/122,112 is based on the thermistor effect, which states that the resistance of a semiconductor material will change with changes in temperature. The KTY81/122,112 is composed of a sintered material, with a core consisting of a nickel-plated, ceramic-based material. The ceramic core is surrounded by metal resistors and other components to provide a high degree of temperature sensitivity.

The thermistor works on the principle that a temperature change will cause a change in the resistance of the ceramic core. When the temperature rises, the resistance of the ceramic core decreases and the metal resistors start to take over, thereby providing a stable voltage over a wide range of temperatures. This is different from other forms of temperature sensors, such as thermocouples, which require a direct connection to a temperature source to measure the change in temperature. With the thermistor however, no external power source is needed as the voltage is generated internally.

Conclusion

The KTY81/122,112 is a highly accurate temperature sensor that is suitable for a wide range of applications including automotive, industrial, medical, communications and power supply systems. Its ability to measure temperatures ranging from below 0°C to 200°C makes it highly reliable. Its working principle is based on the thermistor effect, which states that the resistance of a semiconductor material will change with changes in temperature and is suitable for use as a temperature switch or a temperature measurement element.
