Bimetallic thermometers

The operation of a bimetallic thermometer is based on the principle of two metal plates with different expansion coefficients attached to each other. These metal plates are usually of two different materials, such as copper and iron, welded or soldered together. The unique characteristic of these metals is that they each exhibit different degrees of expansion with changes in temperature. When the temperature increases or decreases, the two metal plates react differently to this change in temperature. The metal with the higher coefficient of expansion will expand more than the metal with the lower coefficient of expansion. This causes the metal plates to bend relative to each other.

This deformation is then converted into movement of the pointer on the dial by means of a mechanical system. The mechanism is designed so that the movement of the metal plates is accurately transferred to the pointer, causing the pointer to indicate the temperature on the scale of the dial.

Bimetallic thermometers are widely used in a variety of applications ranging from simple room thermostats to industrial environments such as oil refineries and heaters. Simple operation, durability and cost-effectiveness make these thermometers suitable for a wide range of applications where accurate temperature measurements are required. They provide a reliable and economical way to measure and display temperature variations.

Marktechnical has the ability to label or imprint your bimetallic thermometer, such as your company logo. This way, you can benefit not only from high-quality measuring instruments, but also from personalized instruments that fit your company's identity.
