![]() ![]() By the way, this is also the reason why they are often called membrane thermostats. The main structural element of almost any room mechanical thermostat is a gas membrane. To make it clearer how it all works, let’s look at the design of a standard room mechanical thermostat. Roughly the same processes take place in a mechanical thermostat, the only difference is that a change in temperature to a certain level, which is indicated by us separately by a regulating wheel, starts certain processes, most often closes or breaks an electrical circuit, what causes turning on or off heating devices. The mercury contained inside the thermometer increases in volume with increasing temperature and enters the graduated capillary, thereby showing the exact temperature. Operating Principle of Mechanical ThermostatĪs an everyday example, familiar to everyone, that would explain the principle of operation of a mechanical thermostat, we can cite an ordinary mercury thermometer, with which we measure body temperature. Mechanical thermostats have one single principle in the operation, and that is the ability of some materials and substances to change their mechanical properties depending on temperature. If you want to know How Analog Thermostat Works, check out this post! The Operating Principle of Mechanical Thermostat How does a mechanical thermostat work, what exactly allows it to measure the temperature of the surrounding space and control electrical appliances? The main feature of the mechanical thermostat is the complete absence of electrical power, i.e. no power is required for its operation, not even batteries. Simply put, a mechanical thermostat, depending on the set program, by turning it on or off certain heating or cooling devices, maintains the required temperature in the room. The main difference between room mechanical thermostats and thermostats of another type is that it is a separate, completely independent device, most often made in the form of an external wiring product, intended for indoor installation. Heating your home to enjoy a certain level of comfort is essential during the winter. But heating your home properly while avoiding exploding your energy bill is even better. To do this, you can opt for the installation of a thermostat, which will ensure the most constant temperature possible to heat your home. At a time when the electronic thermostat is used more and more, does the mechanical thermostat still have an interest? Let’s find out! Working Principle When the strip heats up, it opens the circuit and switches off the heating, which leads to cooling the room down. ![]() ![]() When the strip is cool, the circle is closed, and electricity goes through the connected circuit which leads to switching on the heating. So How Does a Mechanical Thermostat Work? A mechanical thermostat is a device that regulates the heat with the help of the expansion of their internal metallic strips.
