WZPK-266S Bimetal Thermometer with Electrical Contact Product Introduction (English Version)

The WZPK-266S bimetal thermometer with electrical contact is a professional industrial instrument designed for temperature measurement and control applications. Utilizing the thermal expansion principle of bimetal sensing technology, this device provides reliable temperature monitoring and switching functions for various industrial processes through mechanical contact signal output.

Featuring a robust integrated construction, the thermometer s core component consists of precision-engineered bimetal strips. Temperature variations are converted into mechanical pointer movement through differential thermal expansion, delivering clear analog indication on a high-visibility dial. The adjustable contact mechanism enables preset temperature threshold activation, supporting SPDT (Single Pole Double Throw) switching configuration for seamless integration with control systems. The fully sealed housing with vibration-resistant internal components ensures stable operation in demanding environments.

This thermometer offers flexible mounting options including axial, radial or adjustable angle orientations. The standard stainless steel stem is customizable in length, with 304/316 stainless steel wetted parts providing corrosion resistance. The twin-layer safety glass window enhances operational security while maintaining legibility. With a measuring range spanning -80℃ to +500℃ and ±1.5% full scale accuracy, the contact unit handles AC220V 3A (resistive load) for industrial control applications.

Ideal for petrochemical plants, power generation facilities, food processing lines and pharmaceutical equipment, this device excels in scenarios requiring local indication combined with automated control. The mechanical contact system enables intrinsic safety functionality for emergency shutdowns and temperature alarms without external power supply. Designed for low maintenance, routine calibration ensures long-term measurement stability, making it a cost-effective solution for industrial temperature management. The thermometer s durable construction and adaptable design meet diverse operational requirements while maintaining consistent performance under challenging conditions.
