Temperature measurement is one of the most common and necessary applications when it comes to analyzing and measuring a variety of conditions. Especially when it comes to industrial applications, a precise knowledge and understanding of the ambient temperature is essential in ensuring the functionality of an entire system and indirectly, its performance.

Mechanical thermostats are among the most popular solutions when it comes to temperature measurement and control. This type of device is generally based on the bimetallic principle which relies on two metals (typically copper and iron, or nickel and iron) combined together to form a strip. The difference between their expansion coefficients and contraction due to temperature variations causes the metal strip to bend, thus controlling a set of contacts which in turn can be used to control an electrical circuit that actuates a relay. In this way, heaters, cooling systems and other electrical components can be triggered when a certain pre-set temperature is reached.

One of the most popular and commonly used mechanical thermostats is the 345000220109. This device is highly accurate, fast-responding and has an extremely wide temperature range of -60°C to +150°C. It is also designed to be corrosion resistant and has a rugged construction to ensure its durability and stability over time.

When it comes to its working principle, the 345000220109 performs its task by responding to the temperature of its environment through the bimetallic strip. This strip is composed of copper and iron, which, due to their different expansion coefficients, will bend as its active element when the temperature changes. The bending of its active element will then move a contact which will then close or open an electrical circuit, thus controlling the temperature of the environment.

The device also has a set of adjustable contact points which allows for the precise setting of a desired temperature, as well as additional built-in safety mechanisms such as current and voltage protection. This aids in protecting the thermostat from overcurrent, short circuits, current leakage, and voltage spikes.

In conclusion, the 345000220109 is a highly accurate, fast-responding, and reliable device that can is ideal for a wide variety of temperature measurement and control applications. Its bimetallic principle provides much advantages over other types of temperature sensors and its rugged construction ensures its longevity and durability. Additionally, its adjustable contact points, current and voltage protection, and wide temperature range make it the perfect choice for both industrial and laboratory applications.
