英文介紹(English Description)
The WZPK-305S Bimetallic Thermometer with Electrical Contact is designed for industrial temperature monitoring and control, capable of measuring liquids, steam, and gases within -80℃ to +500℃. Its bimetallic strip sensing element ensures precise mechanical contact activation for alarm or circuit interruption functions. The device features a robust stainless steel casing with optional 100mm/60mm dial sizes, supporting axial, radial, or adjustable mounting orientations.
Key functionalities include on-site temperature display, dual-range alarm settings (upper/lower limits), and contacts rated for 220VAC/0.7A or 24VDC loads. The protective tube is constructed with corrosion-resistant materials like 1Cr18Ni9Ti, adaptable to various insertion depths. With IP55 protection and operational stability in -25℃ to +55℃ environments, it suits demanding applications in petrochemical, power generation, and metallurgical sectors.
The thermometer leverages thermal expansion principles to drive pointer movement and contact switching, providing both local reading and remote signal output without external power. Its optimized mechanical design minimizes hysteresis and ensures consistent performance under vibration conditions, while modular construction allows easy maintenance. 41225
