Product Overview
The WZPK-304U Bimetallic Thermometer with Electrical Contact is a precision instrument designed for industrial temperature monitoring and automatic control, capable of measuring liquids, steam, and gases. Its core component consists of laminated bimetallic strips that deform with temperature changes to drive pointer rotation, providing direct reading on the dial. With a measurement range of -80℃ to +500℃, it serves diverse applications in petroleum, chemical, power generation, and machinery industries. 315
Key Features
Featuring a stainless steel casing, the WZPK-304U offers IP55 protection against water ingress and corrosion. The adjustable electrical contacts enable customizable alarm thresholds for automated safety interventions. Its spiral-shaped bimetallic coil ensures ≤40s thermal response time, while axial/radial/universal mounting options adapt to spatial constraints. The vibration-resistant design maintains accuracy in high-motion environments without requiring external power for local indication. 61320
Operational Principle
Temperature variations cause differential expansion of the bimetallic strip, mechanically displacing the pointer along the calibrated scale. Integrated electrical contacts activate when reaching preset limits, triggering relay signals for control circuits. This purely mechanical operation eliminates electronic dependencies, ensuring reliability in harsh conditions. The modular structure allows easy maintenance with replaceable core components. 21026
Typical Applications
Ideal for boilers, reactors, and HVAC systems, this model excels in scenarios requiring vibration tolerance such as marine engineering or compressor stations. Customizable parameters include immersion length (100-2000mm), process connections (NPT/G threads), and dial orientations to match specific installation requirements. The product’s robust construction minimizes maintenance needs while providing long-term stability. 141827
