Product Introduction in English
The WZPK2-235SA Bimetallic Thermometer with Electrical Contact is a precision instrument designed for industrial temperature monitoring and control. Utilizing the bimetallic strip principle, it directly measures temperatures from -80°C to +500°C in liquids, vapors, and gaseous media. This product combines traditional temperature indication with electrical contact functionality, making it ideal for automated process control in petrochemical, power generation, and manufacturing applications where real-time temperature supervision is critical. 419
Key Features
Featuring robust stainless steel construction, the WZPK2-235SA offers reliable mechanical contact operation without complex electronic components. Its vibration-resistant design and corrosion-resistant materials ensure stable performance in harsh industrial environments. The product is available in multiple configurations including axial, radial, and adjustable-angle types to accommodate various installation requirements. With contact rating of 10VA (non-inductive load) and maximum operating voltage of 380V AC, it provides dependable switching capability for control circuits. 51224
Operational Principle
Temperature changes cause differential expansion of the bimetallic coil, which mechanically actuates the contact mechanism. When preset temperature thresholds are reached, the moving contact engages or disengages with fixed limit contacts, triggering control relays in the circuit. The instrument maintains switching accuracy with set point error within 1.5 times of basic error limit and repeatable operation. Its IP55 protection rating ensures proper functioning in ambient conditions from -25°C to +55°C with relative humidity up to 85%. 3715
