WSSX-411 Bimetallic Thermometer with Electrical Contact Product Introduction
The WSSX-411 bimetallic thermometer with electrical contact is an industrial-grade temperature monitoring and control device based on bimetal sensing technology. This product integrates temperature measurement and electrical signal output through mechanical structure design, suitable for industrial applications requiring real-time temperature monitoring and control activation. Featuring an all-stainless-steel enclosure with IP65 protection rating, it demonstrates reliable performance in humid or dusty environments.
The core sensing element consists of two bonded metal strips with different thermal expansion coefficients. Temperature variations induce mechanical deformation, driving the dial pointer to accurately indicate current temperature values. The built-in adjustable electrical contact mechanism allows independent setting of upper/lower alarm thresholds via an external dial knob. When measured temperature exceeds preset limits, the contact system automatically opens or closes control circuits to activate equipment protection, process interlocking or alarm functions. The contact capacity meets standard control circuit requirements with low and stable contact resistance.
Available in axial or radial configurations, the thermometer supports probe lengths from 100mm to 500mm for pipeline or vessel installations. The standardized dial diameter features high-contrast black graduations on white background, ensuring legibility within 5 meters. Covering -40℃ to +500℃ measurement range, its fundamental error remains within ±1.5% of span while maintaining reliable operation under vibration below 25Hz.
This thermometer has been widely implemented in petrochemical equipment, industrial boiler systems, food processing machinery, and HVAC units. Its purely mechanical design ensures long-term stable operation without external power supply. Manufacturing processes adhere to strict quality protocols, with each unit undergoing 72-hour simulated operation tests before delivery to verify measurement consistency and environmental durability.
