Introduction

Temperature sensors, also called thermometers, are devices used throughout many industries to measure temperatures - both of objects and of the environment around them. One type of temperature sensor that is particularly popular is the mechanical thermostat, which is mainly found in home and commercial heating, cooling, and air conditioning systems. In this article, we will take a closer look at the application field and working principle of 300400210018, one of the most popular models of mechanical thermostats.

Application Field

300400210018 mechanical thermostats are primarily used in residential and commercial heating, cooling, and air conditioning systems. By regulating the temperature of a space, this type of thermostat provides a comfortable living or working environment. This type of thermostat is also popular in industrial settings such as factories, warehouses, and other areas where temperature control is important for product quality and safety.

Working Principle

The 300400210018 mechanical thermostat operates using a bi-metallic coil. This coil is made up of two strips of metal with different thermal expansion coefficients. When the temperature surrounding the coil increases, the two strips will expand at different rates, causing the coil to bend. This bending creates tension in a lever that is attached to the coil, and the tension causes a switch to close, which in turn turns on the heating/cooling system.

When the temperature has risen to the desired level, a fixed contact point on the switch will open, causing the heating/cooling system to shut off. When the temperature begins to drop, the bi-metallic coil will relax, releasing the tension on the lever and opening the switch again, turning the system back on. This cycle repeats as needed to maintain the desired temperature.

Conclusion

The 300400210018 mechanical thermostat is widely used in residential and commercial HVAC systems to regulate the temperature in an area. It utilizes a bi-metallic coil and lever-controlled switch to automate the process of turning the HVAC system on and off, allowing for precise temperature control. This type of thermostat is a reliable and cost-effective way to keep a comfortable atmosphere in any environment.
