5" 125mm Meat Grill Bimetallic Thermometer Food

Meat Thermometer-Grill Thermometer-Bimetal Thermometer

Principle

The bimetallic thermometer consists of a bimetallic strip. A bimetallic strip is made of two thin strips of metals which have different coeffcients of expansion. The two metal strips are joined together by brazing, welding or reveting so that the relative motion between them is arrested.

The bimetallic strip is in the form of a cantilever beam. An increase in temperature will result in the deflection of the free end of the strip as shown i diagram. This deflection is linear and can be related to temperature changes.

The radius of the curvature of the bimetallic strip which was initially flat is determined using the following relationship.

R= t{3(1+m)² + (1+mn)[m²+1/mn]}/6(ah-al)(T2-T1)(1+m) ²

Industrial bimetal thermometer adopts a multilayer metal sheet as temperature-sensing element to control the pointer. The multilayer metal sheet is formed by two (or more) metal sheets that are laminated together. The element works on the principle that two different metal expand in different amounts when temperature changes. For example, there are two winded and ring-shaped metal sheets. One metal sheet expands with heat and drives the pointer to rotate, and then the instrument shows the temperature number corresponding to thermoelectric potential.
Bimetal thermometer is widely used in petroleum and chemical industry and other fields. And it is available in corrosive medium and conditions.
