Bimallilämpömittarit

Bimallilämpömittarit, also known as bimetallic strip thermometers, are devices used to measure temperature. They operate on the principle that different metals expand at different rates when heated. A bimetallic strip is constructed from two dissimilar metals, typically brass and steel or copper and steel, bonded together along their length. When the temperature changes, one metal expands or contracts more than the other. This differential expansion causes the strip to bend.

The degree of bending is directly proportional to the temperature change. This bending motion is then used to move a pointer across a calibrated scale, indicating the temperature. The scale is usually marked in degrees Celsius or Fahrenheit. Bimallilämpömittarit are commonly found in applications where a robust and relatively inexpensive temperature gauge is required, such as in ovens, thermostats, and some industrial processes. They are known for their durability and lack of need for external power. However, their accuracy can be affected by factors like pressure and the speed of temperature change, making them less suitable for highly precise measurements compared to other thermometer types. They are generally considered reliable for general-purpose temperature monitoring.
