The WSS-481 bimetal thermometer is an industrial-grade temperature measurement instrument based on thermal expansion principles, designed for reliable temperature monitoring in various complex working conditions. Utilizing a bimetallic strip as the core sensing element, this device translates material deformation caused by temperature changes into precise pointer readings, offering intuitive operation and low maintenance requirements.
The stainless steel casing features integrated molding technology with anti-corrosion surface treatment, ensuring stable performance across a broad temperature range from -20℃ to 500℃. The high-contrast dial combines white background with black graduations, providing clear Celsius and Fahrenheit dual-scale readings. Enhanced vibration resistance structure maintains measurement accuracy under mechanical stress, while IP65 protection rating guarantees reliable operation in humid or dusty environments.
This thermometer series demonstrates exceptional adaptability across multiple industries, including pipeline temperature monitoring in petrochemical facilities, equipment status tracking in power systems, thermal efficiency analysis for HVAC installations, and process control in food production lines. Three orientation configurations (axial, radial, and adjustable) are available with multiple connection interfaces such as M20×1.5 thread, G1/2 thread, and flange adapters, compatible with pipe diameters from DN15 to DN100.
Manufacturing processes incorporate specialized annealing treatment for the thermal element to optimize responsiveness and durability. Toughened glass lens resists high temperatures and mechanical impacts, while low-friction bearing mechanism prevents pointer sticking. Rigorous quality control procedures include thermal aging tests and cryogenic cycling verification, maintaining measurement deviation within ±1.5% of full scale.
Customization options cover temperature range adjustment, dial diameter modification (standard 80mm), and interface configuration. The maintenance-free design requires only occasional surface cleaning, effectively reducing operational costs. This product series provides an economical solution for industrial applications demanding reliable temperature indication without complex calibration procedures.
