（English Product Introduction）
The WZP-430B Bimetallic Thermometer with Electrical Contact is an industrial-grade temperature monitoring instrument integrating mechanical sensing and electrical control functions. Utilizing the bimetallic strip sensing principle, the mechanical deformation caused by temperature variation drives the pointer rotation, while the built-in adjustable electrical contact device enables dual functionality of local temperature indication and remote signal transmission. This product demonstrates reliable performance in process control systems across various industrial temperature monitoring applications.
Featuring an all-metal casing with double-layer sealing design, the housing surface undergoes anti-corrosion treatment to maintain stable operation within ambient temperatures ranging from -40℃ to +500℃. The standard 100mm dial adopts high-contrast black scale markings on a white background for clear visual reading. The stainless steel sensing element works in coordination with precision gear transmission mechanisms, ensuring temperature indication accuracy within ±1.5% of full scale. The electrical contact system employs silver alloy contacts, capable of sustaining up to 250V AC voltage and 3A current load with reliable electrical conductivity.
Notable product features include: Adjustable mounting bracket on the housing top allowing axial/radial multi-angle installation; High-temperature resistant tempered glass window with shock-absorbing cushion; Luminous coating on the pointer tip for low-light visibility. The contact adjustment knob is equipped with a tamper-proof cover, enabling precise setting of upper/lower alarm limits through specialized tools with adjustment accuracy reaching ±0.5% of scale range. The entire unit meets IP65 protection level, ensuring continuous operation in dusty environments or under water spray conditions.
This model is widely implemented in temperature interlock protection for petrochemical equipment, sterilization temperature monitoring in food/pharmaceutical facilities, and overheat protection in HVAC systems. Customizable options include stainless steel 304/316L housing materials and contact configurations (single upper/lower limit or dual limits). Each unit undergoes 72-hour continuous operational simulation testing prior to shipment, guaranteeing operational stability under transportation vibration and sudden temperature fluctuation conditions.
