WSS-561 Bimetal Thermometer Product Introduction
The WSS-561 series bimetal thermometer is a cost-effective temperature measurement instrument specifically designed for industrial applications. Utilizing the classic bimetal sensing principle, it achieves precise temperature indication through differential thermal expansion of metal strips. The optimized mechanical structure balances functionality and affordability, making it suitable for various routine temperature monitoring scenarios.
Constructed with 304 stainless steel housing featuring polished surface treatment, this thermometer demonstrates both corrosion resistance and mechanical durability. The 60mm diameter dial with black graduations on white background ensures clear readability within -20℃ to 500℃ range (customizable scales available). Tempered glass window enhances impact resistance for extended service life. The sensing probe offers flexible configuration options including axial, radial, or adjustable type to accommodate different installation requirements on pipelines and equipment.
Key advantages lie in its reliable mechanical design that operates without external power supply, making it ideal for basic temperature monitoring in power generation, petrochemical, and HVAC systems. Integral probe and protective tube construction minimizes measurement deviation caused by medium corrosion. Fully enclosed structure provides protection against dust, moisture, and moderate vibration in standard industrial environments.
The WSS-561 emphasizes user-friendly features: Detachable bezel allows multi-angle reading adjustment while 135° rotatable head facilitates post-installation viewing angle optimization. Pre-delivery thermal cycling tests guarantee stable performance between -20℃ to 80℃ ambient temperatures. Recommended for local temperature indication in heat distribution networks, mechanical equipment, and storage tanks. Protective wells are suggested when measuring corrosive media.
