工作原理（Working Principle）
The WZPK-233U bimetal thermometer operates based on differential thermal expansion principle: two bonded metal strips with distinct expansion coefficients form a helical sensing element. As temperature changes, the helical coil winds or unwinds to drive the pointer rotation, displaying real-time temperature on calibrated dial. The integrated electrical contacts trigger at preset temperature thresholds, activating control circuits without external power supply. This mechanical action ensures reliable operation even in high-interference environments.1228
