Introduction to the 66L045 Application Field and Working Principle
The 66L045 is a temperature sensing element used to sense temperature at inlet or outlet temperatures of piping systems. It is classified as an electronic thermocouple type sensor and is typically used in temperature protection relays, oil circuit breakers, motor controllers, and temperature detectors. It is available in a wide variety of models, including NTC type, PTC type, electro-mechanical type, and non-contact type. As an electronic temperature sensing element, it has the characteristics of high accuracy, high sensitivity, and long service life.Features of the 66L045
The 66L045 is equipped with an open or N-type temperature element with an accuracy of ±0.5-1°C. It has a wide temperature range of -30°C to +120°C with a maximum ambient temperature of +80°C. It features a small size and low power consumption, and can be easily mounted on the corresponding panel or on the equipment to be measured. In addition, it has a fast response time of less than 1 second.Working Principle of the 66L045
The 66L045 is usually used to measure inlet and outlet temperatures of piping systems. It works by regulating the rate of electrical current through its resistance to control the temperature of the object being measured. The thermocouple type sensor consists of two electrodes, one positive and one negative and a resistive wire. When the temperature of the object being measured changes, the resistance across the wire changes, causing a change in current through the wire. This change is then detected and compared with the set temperature to determine whether the temperature is within range or not. If the temperature is outside the predetermined range, an alarm is triggered.Applications of the 66L045
The 66L045 is widely used in a variety of applications that require fast response and accurate temperature measurement. It is used in temperature protection relays, oil circuit breakers, motor controllers, and temperature detectors. It is also used in water and oil tanks, air conditioners, furnaces, fuel tanks, and refrigerators. It has become an invaluable tool in the maintenance of safety in many industries.Conclusion
The 66L045 temperature sensing element is a reliable and accurate device for measuring temperature. It comes in a range of models, including NTC type, PTC type, electro-mechanical type, and non-contact type. It features fast response time, high accuracy, and long operating life, and is easy to install. Its wide range of applications make it an invaluable tool for the proper functioning and maintenance of many industries.
