[English Product Introduction]
The WZPK2-175SA Bimetallic Temperature Switch is a precision instrument designed for industrial process temperature monitoring, employing helical bimetallic strip sensing technology to achieve mechanical conversion of temperature parameters. This device translates thermal variations into visible pointer readings through optimized mechanical construction, featuring adjustable electrical contacts for temperature control applications requiring signal output.
Constructed with corrosion-resistant metal composites, the housing adopts precision stamping technology to achieve IP65 protection rating, effectively resisting dust ingress and water jet exposure. The bimetallic sensing system undergoes specialized heat treatment processes, delivering linear temperature response within -50℃ to 500℃ range with pointer hysteresis controlled within ±1.5% of span. The contact module utilizes silver alloy material maintaining stable contact resistance below 50mΩ, supporting electrical loads up to 250V AC/3A.
Featuring radial mounting configuration, the instrument incorporates a 75mm diameter dial and 175mm sensing probe length suitable for standard industrial installations. Shock-resistant tempered glass cover ensures stable operation under vibration conditions below 55Hz frequency and 1mm amplitude. Customizable probe options include 304/316 stainless steel materials with optional threaded or flanged connections for diverse medium measurement requirements.
This thermometer is ideal for reactor temperature monitoring in petrochemical plants, sterilization process tracking in food processing equipment, and overheat protection in HVAC systems. Dual adjustable setpoint knobs allow users to define upper/lower alarm thresholds, enabling equipment interlocking via relay modules. Analog display eliminates deviation risks from electronic component aging, while mechanical architecture ensures basic monitoring functionality without external power supply.
The product emphasizes structural reliability through cold-forged pressure components and vacuum-sealed movement assembly. Special attention is given to thermal expansion compensation design, ensuring measurement stability during rapid temperature fluctuations. Optional magnetic drive coupling configuration provides galvanic isolation for explosive environments. Periodic maintenance recommendations include annual bearing lubrication and triennial contact resistance verification to sustain long-term operational accuracy.
