Introduction

66L090-0499 is a temperature sensor belonging to the thermostat family of temperature sensors. It is a mechanical temperature sensor, meaning that it senses temperature through physical contact. This makes it better suited for applications where high accuracy and direct measurement are required. It also has the advantage of being cheaper than other temperature sensors due to its relatively simple construction.

Application Field

66L090-0499 is used in applications requiring a highly accurate and direct measurement of temperature. It is typically used for applications such as controlling HVAC systems, controlling water temperatures, and monitoring temperatures in industrial environments.

How It Works

The 66L090-0499 temperature sensor is a mechanical device that consists of an inner and outer body. The outer body houses two temperature sensing contacts and the inner body contains a bi-metallic strip. The bi-metallic strip is made of two different metals which expand and contract differently according to temperature, causing the strip to bend when the temperatures around it change.When the temperature around the sensor changes, the bi-metallic strip bends, causing the two temperature sensing contacts to move closer or farther apart and thus creating a circuit. This circuit changes resistance depending on the temperature, and can be used to measure and control temperature in a variety of different ways.

Conclusion

The 66L090-0499 temperature sensor is a versatile and inexpensive temperature sensing device that can be used in a variety of applications. Its mechanical construction gives it the advantage of being able to withstand high temperatures and provide a highly accurate direct measurement of temperature. Its simple and inexpensive construction make it an ideal choice for applications where high accuracy and direct temperature measurement are required.
