Temperature Sensors - Thermostats - Mechanical

Temperature sensors and thermostats play an important role in many industries and applications. Because of their basic functionality they are often used to measure and manipulate temperature and control systems. With the advance of technology, mechanical temperature sensors and thermostats are becoming increasingly more efficient, accurate, and reliable.

A temperature sensor is a device that measures temperature and sends a corresponding signal that can be interpreted by a controlling system. Mechanical models rely on direct measurement, using principles of thermodynamics to detect heat energy. The most common type is the bimetallic temperature sensor. It consists of two metallic strips fused together, each of them is made from different metals (usually one from each side of the galvanic series). When temperature rises, the bimetal strip bends in one direction or another according to the metals that are used. This change can be monitored and used to turn on/off certain devices or send signals to other devices.

A thermostat is a device which maintains a desired temperature by regulating the flow of heat energy. It automatically shuts off or opens a heater, air conditioner or radiator when the temperature reaches a preset level. Electric and electronic thermostats are the most common in modern applications, but mechanical models are still widely used due to their simplicity and reliability. Mechanical thermostats have a bimetallic strip inside that reacts to temperature changes. When temperature rises the strip bends, bending the contact between two leads, thus opening/closing the circuit and shutting off/opening the device.

Mechanical temperature sensors and thermostats are widely used in many industries and fields such as heating/cooling systems, electrical equipment, HVAC, medical devices, laboratory controls, automotive, aerospace applications, and more. In safety critical systems they can provide reliable and accurate temperature control.

Thanks to modern technology mechanical temperature sensors and thermostats became more efficient and accurate than ever before. They provide reliable temperature control in many critical applications and fields of industry, ensuring safety and smooth operation of a wide range of systems.
