Bimetallic thermometer, pressure type thermometer structure difference

Bimetallic thermometer manufacturers instrument is bimetallic thermometer manufacturers, main products are winding thermometer and pressure type thermometer, but the two difference between bimetallic thermometer or contact, there are few articles to specific analysis. Bimetallic thermometer manufacturers analysis for everyone before 'pressure type thermometer compared with bimetallic thermometer principle', from the working principle of the theory to distinguish the bimetallic thermometer and pressure type thermometer, and then the last analysis, analysis of bimetallic thermometer for everybody today, pressure type thermometer structural difference. Pressure type thermometer mainly by measuring your bag, capillary, bourdon tube parts and instructions. Work pressure type thermometer features is generally determined by the filling material, when filling material for gas, Generally for nitrogen) , as a result of the nitrogen pressure coefficient can be approximately regarded as an ideal gas. Linear relationship between pressure and temperature, so scale indicator for uniform linear scale.

bimetallic thermometer is usually around a spiral ( Straight spiral or flat spiral) The thermal element - Bimetallic strip, connecting rod, a pointer shaft, instruction sheet parts and protecting tube, etc.

bimetallic thermometer performance is mainly determined by the physical properties of the bimetallic strip. When a bimetallic strip in linear (within the scope of its amount of displacement Or deflection Angle) A linear relationship with temperature, dial scale is uniform. The nonlinear temperature range, the bending decreases with the rise of temperature.
