电接点双金属温度计 WZPK-306S 产品介绍（英文）
The WZPK-306S Bimetallic Thermometer with Electrical Contact is an integrated field instrument combining temperature measurement and control functions, widely used in temperature monitoring applications across food processing, chemical production, HVAC systems, and mechanical manufacturing industries. Utilizing bimetal spiral coils as the core sensing element, this device converts temperature variations into pointer movement through a mechanical transmission system, complemented by adjustable electrical contacts to achieve visual temperature indication and automated process control.
Key features include: 1) High-sensitivity bimetal sensing coil enabling rapid response to temperature changes with ±1.5% full scale accuracy; 2) Housing constructed from 304 stainless steel or reinforced aluminum alloy with anti-corrosion treatment, suitable for operating temperatures ranging from -40℃ to +500℃; 3) Fully sealed enclosure design achieving IP65 protection rating, effectively resisting dust ingress and water spray; 4) Electrical contact system employing silver alloy contacts, configurable for single upper/lower limit or dual limit settings with 220VAC/3A switching capacity (resistive load); 5) Flexible installation options including axial, radial, and adjustable gland orientations, compatible with M27×2, G1/2 and other process connections.
The product emphasizes vibration resistance and long-term stability for industrial environments. Incorporating wear-resistant alloy bearings in the transmission mechanism and precision calibration processes ensures reliable indication under mechanical vibration conditions. The anti-glare dial features a dual-layer design with white background and black graduations, improving readability by 30% compared to conventional models. Independent adjustment knobs on the contact setting mechanism allow real-time comparison between preset values and actual readings, minimizing operational errors.
Customization options include: 60mm/100mm/150mm dial diameters; multiple process connections (flange, threaded, or clamp-type); configurable contact output modes (NO/NC combinations). Each unit undergoes 72-hour simulated operational testing prior to delivery to verify performance compliance with design specifications.
