工作原理
WZPK-363S基于热膨胀原理工作,其核心部件是由两种不同膨胀系数的金属片复合而成的螺旋状感温元件。当温度变化时,双金属片因热膨胀差异产生形变,带动连接轴转动并驱动指针指示对应温度值。电接点装置与指针联动,当指针到达预设的上下限温度位置时,机械触点会闭合或断开,从而触发外部控制电路。这种纯机械结构的设计方案确保了产品在复杂电磁环境下的稳定性和抗干扰能力。316
Product Introduction
The WZPK-363S Bimetallic Thermometer with Electrical Contact is a robust industrial instrument designed for temperature monitoring and control applications. Its bimetallic sensing element provides reliable measurement of liquid, steam and gas temperatures within -80℃ to +500℃ range. The product features a stainless steel construction with IP55 protection grade, making it suitable for use in demanding environments such as petrochemical plants, power stations and mechanical workshops. Clear dial indication and adjustable contact settings enable convenient on-site operation. 1015
Functional Features
This thermometer combines temperature indication and electrical switching functions in one compact device. The corrosion-resistant case houses a precision bimetallic coil that ensures fast response to temperature changes. Electrical contacts are actuated when the temperature reaches preset values, triggering control circuits without external power supply. Available in axial, radial and adjustable angle configurations, it supports flexible installation in pipelines or equipment. The vibration-resistant design maintains measurement stability even in high-vibration environments. Dial sizes from 60mm to 150mm cater to different visibility requirements. 132026
Operational Principle
At the heart of WZPK-363S lies a spirally wound bimetallic strip that twists proportionally to temperature changes. This mechanical movement rotates the pointer across a calibrated scale while simultaneously activating the electrical contacts at user-defined setpoints. The completely mechanical operation ensures fail-safe performance without electronic components. Contact ratings support standard control voltages, providing reliable switching for alarms or process control systems. Maintenance-free operation and long service life make this product a cost-effective solution for industrial temperature monitoring. 111722
