Temperature measurement is the core link to ensure production safety and process stability in industries such as petrochemicals, machinery manufacturing, and power energy. TiankangWSSBimetallic thermometers, with their unique technological advantages and reliable quality, have become the preferred tool for on-site temperature measurement in medium and low temperature scenarios. This article will analyze the excellent performance of this instrument from four dimensions: working principle, core advantages, application scenarios, and technical characteristics.

1、 Principle of bimetallic thermal expansion: the physical basis for precise temperature measurement

TiankangWSSThe core component of a bimetallic thermometer is a spiral coil shaped thermal bimetallic strip, which is composed of two metals with significantly different coefficients of linear expansion (such as nickel chromium alloy and nickel silicon alloy) that are composite through precision welding technology. When the temperature changes, the two metals undergo bending deformation due to their different coefficients of expansion, which drives the pointer fixed at the free end to rotate and directly displays the temperature value on the circular scale. This physical driving method does not require an external power source, has natural resistance to electromagnetic interference, and has a response time≤40In seconds, it can quickly capture temperature fluctuations.

To improve temperature sensitivity, Tiankang adopts multi-layer metal sheet stacking technology, which enables the spiral coil structure to undergo significant deformation under small temperature changes. for example, in-80℃to+500℃Within a wide range, the error is controlled within the range1%Within, meetGB3836-83WithJB/T8803-1998Double standard requirements.
