The Bimetallic Temperature Gauge operates on the basis of coefficient of thermal expansion of metals. The bi-metal the coil is manufactured from two cold-welded metal strips with different thermal expansion coefficients, which rotate in proportion to temperature. The rotary movement is conveyed to the pointer via a frictionless assembly. A comprehensive range of the standard version facilitates a variety of applications and uses. Adhering to the EN13190 standard, the design and construction of the
bimetallic temperature gauge offers a robust and reliable means of temperature measurement with quick response time.
