本系列产品特别注重使用便捷性，支持现场校准功能，无需拆卸即可通过表盘调节螺钉微调精度。接点容量设计合理，可直接驱动小型继电器或信号模块，减少中间转换环节。产品出厂前均通过多道工序检测，确保测量误差控制在±1.5%量程范围内。适用于蒸汽系统、反应釜、管道设备等需要温度监测与联锁控制的工业场景，为用户提供经济实用的温度管理解决方案。
【English Version】The WZPK-376S Bimetallic Temperature Switch with Electrical Contact is a precision instrument designed for industrial temperature monitoring and control applications. It is widely used in petrochemical plants, power generation systems, mechanical equipment and food processing facilities for reliable temperature management.
This instrument integrates a bimetallic sensing element with mechanical transmission and electrical contact technology. The spiral-shaped bimetallic strip drives the pointer movement through thermal expansion/contraction, providing direct temperature reading on the high-visibility dial. The scratch-resistant glass window and corrosion-resistant stainless steel case (304 grade) ensure long-term durability in harsh environments. Silver alloy contacts with low resistance characteristics enable precise switching at preset temperature thresholds.
Featuring adjustable installation configurations (axial, radial or adjustable angle), the thermometer accepts customized probe lengths from 60mm to 400mm to suit various immersion requirements. The hermetically sealed construction provides IP65 protection against dust and water spray. Operating within -20℃ to +500℃ range, it maintains stable performance under vibration and temperature fluctuation conditions.
Field calibration capability allows accuracy adjustment (±1.5% full scale) via calibration screw without disassembly. The SPDT contact configuration supports direct control of alarms or equipment with 220VAC/3A switching capacity. Optimized mechanical design reduces hysteresis effect while ensuring fast response to temperature changes. Typical applications include steam pipelines, reactor vessels, heat exchangers and other industrial systems requiring temperature indication with safety interlock functions.
