Understanding Mechanical Temperature Controllers

Mechanical Temperature Controllers: An Introduction

Temperature control is a crucial aspect of various industrial and domestic processes. Whether it’s maintaining the right temperature in your home, regulating the temperature of a chemical reaction, or ensuring the optimal conditions in a greenhouse, temperature controllers play a vital role. Among the various types of temperature controllers available, mechanical temperature controllers stand out as a reliable and cost-effective option. In this article, we will delve into the world of mechanical temperature controllers, exploring how they work, their applications, advantages, and limitations. How Do Mechanical Temperature Controllers Work? Mechanical temperature controllers, often referred to as bi-metal thermostats or capillary thermostats, function on a simple yet effective principle. At the core of these controllers is a bimetallic strip, typically made from two different metals with different thermal expansion rates. When exposed to temperature changes, this strip bends due to the varying expansion of its constituent metals. This bending action is utilized to control electrical contacts, either opening or closing a circuit.
