What should you know about bimetallic thermometers? The bimetallic thermometer is considered the temperature management tool which converts the media’s temperature into mechanical displacement. This bimetal thermometer contains 2 different metals, which have different coefficients of thermal expansion. Bimetallic thermometers are mostly used in residential devices like ovens, air conditioners, and industrial devices like hot wires, heaters, refineries, etc. This V-Line Thermometer is durable and offers a cost-efficient way of measuring temperature. In the below section, we will share some more information about the construction and the advantages of bimetallic thermometers. Construction & design of bimetallic thermometer: A bimetallic thermometer works based on 2 basic metal properties: thermal expansion property and the co-efficient of thermal expansion. The bimetallic strip is the major component of the thermometer which contains 2 strips of different metals, including copper and steel. These Pressure Gauge Syphon strips are fixed from one end and free to move from the other side. The thermal expansion is different; the length of the metal changes even at the same temperature. This thermometer is designed so that when the temperature is high, the strip bends to the metal direction with a lower coefficient. But when the temperature decreases, this strip will bend to the metal direction with higher temperature co-efficient. So, do you want to know why this thermometer or Sanitary thermowell is used and what the pros are? How to select the bimetallic thermometer?
Temperature range: While buying a thermometer, make sure it should have the upper and lower limit of temperature. If the temperature is high, the metal can reach the expansion limit and permanently damage the thermometer.
Stem: The length of the stem for the bimetallic thermometer should be based on the application. You should also look for the thermowell, which comes in a cylindrical tube fitting that protects the temperature sensors installed in the industrial tools.
