Product Introduction of WZPK-166U Bimetallic Thermometer with Electrical Contact
The WZPK-166U bimetallic thermometer with electrical contact is a mechanical temperature measurement instrument specifically designed for industrial monitoring and control applications. Utilizing the thermal expansion principle of bimetallic strips, this device integrates temperature indication with electrical signal output capabilities, providing reliable temperature management solutions for various industrial automation systems.
Constructed with a fully sealed stainless steel housing, the instrument features corrosion-resistant surface treatment to ensure stable performance in humid, dusty, and mildly corrosive environments. The dial incorporates high-visibility graduated markings and a dual-pointer system, where fluorescent pointers against a matte black background enable clear readings under low-light conditions or at long distances. The core sensing element consists of specially bonded alloy strips that drive mechanical transmission components, guaranteeing prompt and continuous temperature response.
Equipped with an adjustable electrical contact system, users can independently set upper/lower alarm thresholds via an external rotary knob. When the measured temperature reaches preset values, the contact mechanism activates switching signals to initiate audible/visual alarms, equipment shutdown sequences, or interlock protection functions. Silver-alloy contact components ensure optimal conductivity and wear resistance, significantly extending electrical service life.
This thermometer is suitable for temperature monitoring in pipelines, storage tanks, reactors, and similar industrial equipment. Typical applications include process control in petrochemical plants, thermal protection for power generation facilities, temperature supervision in food processing lines, and HVAC system management. Standard models cover a measurement range from -50℃ to 500℃, with customizable options available for extended ranges. The instrument features an M27×2 external thread connection as standard, compatible with universal industrial installations, while flange-mounted variants are offered for specialized application requirements.
Design emphasis has been placed on operational convenience and maintenance reliability. A sealed calibration window on the housing top allows contact position adjustment without disassembling the device. The dual-layer vibration-damping structure effectively minimizes mechanical oscillation interference, maintaining pointer stability during equipment operation. Each unit undergoes multiple quality verification processes before shipment, with particular attention to temperature indication accuracy and contact activation precision, striving to deliver trustworthy measurement performance for industrial users.
