Bi-metal thermometer WSS series

dialexplosion-proofIP55

YUNYI bimetallic thermometer is a mechanical temperature measurement instrument based on the thermal expansion principle of a bimetallic strip. Its core component is a spiral or helical bimetallic strip composed of two metals with different coefficients of thermal expansion. When temperature changes, the differing expansion rates of the two metals cause the bimetallic strip to bend. This deformation drives a pointer via a transmission mechanism to indicate the corresponding temperature value. Requiring no power source, featuring a robust construction, and providing intuitive readings, this product serves as the most economical and practical on-site temperature indicator for various industrial applications. Product Advantages 1. No External Power Required: Pure mechanical structure requires no power supply; ready to use upon installation, reducing operating costs 2. Rugged and Durable Construction: All-metal design withstands vibration and impact, suitable for harsh industrial environments 3. Intuitive and Reliable Readings: Dial pointer display offers clear, visual readings with no risk of electronic component failure 4. Simple Maintenance: Calibration-free and virtually maintenance-free with extended service life 5. High cost-effectiveness: Economically priced, offering the most economical solution for on-site temperature measurement 6. Safe and reliable: Spark-free design suitable for explosion-proof applications Core Application Areas ✅ Petrochemical Industry: Local temperature display for pipelines, storage tanks, and reactors ✅ HVAC Systems: Temperature monitoring for heating systems, ventilation equipment, and air conditioning units
