The WTC/J length and Angle sensor is a high-performance monitoring device specially designed by Weite Technology Co., Ltd. for lifting machinery. It integrates length measurement and Angle detection, providing precise position data and safety guarantees for crane operations.
Product Overview
The WTC/J length and Angle sensor adopts advanced sensing technology and can precisely measure the extension length and elevation Angle of the crane boom simultaneously. The product features an IP68 ultra-high protection level and is suitable for various harsh working conditions. It is an indispensable key component in the intelligent control system of modern lifting machinery.
Core functional features
Dual-parameter precise measurement
- Length measurementAccurately detect the telescopic length of the crane boom, with a measurement range of 0 to 45 meters
- Angle detectionReal-time monitoring of the boom elevation Angle, with a measurement range of -10° to 90°
- Multi-signal outputIt simultaneously provides three independent signal transmission channels and outputs standard signals ranging from 0 to 10V
Outstanding performance
- High-precision measurementLength nonlinearity ≤0.2%, Angle nonlinearity ≤0.15°
- Strong environmental adaptabilityWith an IP68 protection rating, it is completely dust-proof and water-proof, suitable for harsh outdoor environments
- Stable and reliableAdopting high-quality materials and precise manufacturing processes, it ensures long-term stable operation
