【English Product Introduction】
The WSS-302 bimetal thermometer series is a mechanical temperature measurement instrument developed based on the thermal bimetal principle, widely applied in industrial temperature monitoring scenarios. Featuring an integrated dial structure design, it achieves precise temperature indication through differential metal thermal expansion coefficients without requiring external power supply, making it particularly suitable for equipment temperature monitoring in power generation, chemical processing, and machinery manufacturing industries.
The core component utilizes multi-layer composite metal sensing strips manufactured through precision machining processes, enabling temperature measurement across a broad range from -80°C to 600°C. The 304 stainless steel housing with dual-sealing structure provides IP65 protection rating, effectively resisting moisture and dust erosion. Tempered glass dial with anti-fog coating maintains clear readability under low-temperature or rapid temperature fluctuation conditions. Specially balanced pointer system demonstrates excellent anti-vibration performance for long-term stable operation in turbulent environments.
To accommodate diverse installation requirements, the WSS-302 series offers multiple dial orientations including axial, radial, and universal configurations, supporting thread, flange, and compression fittings. Sensing probe length can be customized up to 2 meters according to specific working conditions. Each unit undergoes multi-stage temperature calibration procedures in constant-temperature environments, maintaining indication error within ±1.5% across the full measurement range. The user-friendly dial layout incorporates high-contrast color zoning and luminous pointer design for quick reading under various lighting conditions.
Emphasizing operational safety, all media-contact metal components undergo passivation treatment to prevent material degradation when measuring corrosive substances. For high-temperature/pressure environments, optional heat dissipation tubes or condensation loops effectively reduce thermal impact on the dial assembly. Maintenance-friendly design allows routine cleaning and basic inspection without specialized tools, significantly reducing end-users maintenance costs.
The product demonstrates stable performance in long-term continuous operation scenarios, with average service life exceeding 50,000 hours under normal working conditions. Flexible customization options include dial size variants (60mm/100mm/150mm), customized scale ranges, and special material versions for extreme environments, providing reliable temperature monitoring solutions for diversified industrial applications.
