The WTC/J Length and Angle Sensor is a high-performance monitoring device exclusively designed by Weite Technology Co., Ltd. for hoisting machinery. Integrating length measurement and angle detection in one unit, it provides precise position data and safety assurance for crane operations.
Product Overview
Adopting advanced sensing technology, the WTC/J Length and Angle Sensor can accurately measure the telescopic length and luffing angle of crane booms simultaneously. Boasting an ultra-high IP68 protection rating, the product is suitable for various harsh working conditions and serves as an indispensable core component in the intelligent control systems of modern hoisting machinery.
Core Functions & Features
Dual-parameter precise measurement
- Length measurement: Precisely detects the telescopic length of crane booms with a measuring range of 0-45 meters.
- Angle detection: Monitors the luffing angle of booms in real time with a measuring range of -10° to 90°.
- Multi-signal output: Delivers 3 independent channels of signal transmission simultaneously, outputting standard 0-10V signals.
Excellent Performance
- High-precision measurement: Length nonlinearity ≤ 0.2%, angle nonlinearity ≤ 0.15°.
- Strong environmental adaptability: IP68 protection rating ensures complete dust and water resistance, suitable for harsh outdoor environments.
- Stable and Reliable: Premium materials and precision manufacturing processes guarantee long-term stable operation.
