WZPK-334S Bimetal Thermostat with Electrical Contact (English Version)

The WZPK-334S bimetal thermostat with electrical contact is an integrated instrument designed for industrial temperature monitoring and control applications. Utilizing bimetal sensing technology combined with electrical contact signal transmission, it provides real-time temperature tracking and automated management capabilities. The stainless steel housing, crafted through precision stamping processes with optional polished or matte finishes, ensures corrosion resistance and mechanical durability for prolonged operation in demanding environments.

At its core lies a high-precision helical bimetal sensor that converts thermal expansion differentials into mechanical displacement. This motion is amplified through precision gear trains to drive the dial pointer. The laser-etched dial features high-contrast black numerals on a white background, offering 270-degree visibility for clear long-distance observation. The adjustable upper/lower limit contacts allow users to set customized alarm thresholds via specialized tools. When temperature exceeds preset ranges, the contact system triggers switch signals to activate external control circuits or warning devices.

Practical safety features include silicone oil-filled casing to dampen vibration interference and maintain pointer stability under industrial shock conditions. Detachable probes with optional materials (304/316L stainless steel, Monel alloy) adapt to high-temperature, high-pressure or corrosive media. Multiple installation options cover threaded connections, flange mounting or customized interfaces, compatible with DN15-DN100 pipeline specifications.

This model finds extensive applications in petrochemical plants, power generation facilities, and food/pharmaceutical processing units for critical tasks such as reactor temperature interlock protection, steam pipeline overheat alarms, and refrigeration unit thermal management. Each unit undergoes rigorous quality assurance procedures including full-scale accuracy calibration and contact repeatability testing, guaranteeing measurement deviation within ±1.5%FS and contact actuation consistency below 0.5% error. Optimized mechanical design ensures reliable performance across a -40℃ to 500℃ range, with contact ratings supporting AC 220V/1A loads for standard industrial control systems.
