二、Technical Highlights & Specification Advantages
- Frictionless Measurement Architecture
The sensor’s magnetic core is fully decoupled from the coil assembly, eliminating mechanical wear. This design enables infinite resolution and superior dynamic response, critical for high-bandwidth displacement measurement in real-time control loops. - Exceptional Linearity and Stability
Utilizing precision winding techniques and electromagnetic shielding, the LS40 achieves full-scale linearity error within 0.25% (higher precision optional). This guarantees accurate and reliable displacement feedback for closed-loop control and structural monitoring systems. - Industrial-Grade Stainless Steel Housing
Constructed from 304/316L stainless steel, the enclosure provides outstanding corrosion resistance and EMI immunity. Optional IP67/IP68 ingress protection ensures continuous operation in oil-contaminated, dusty, or high-humidity environments. - Broad Environmental Compatibility
The sensor supports a standard operating temperature range of -40°C to +125°C, suitable for applications from precision laboratory measurements to subsurface exploration instrumentation.
