Wireless Dual-Beam Automatic Deflection Recorder

无线双侧自动弯沉测定仪

Expressway acceptance often calls for hundreds of deflection points a day across both wheel paths. This set uses two 5.4 m beams with digital sensors reading 0–20 mm at 0.001 mm, sending data wirelessly up to 100 m to a rugged tablet. With GPS station tagging, a two-person crew can cover up to 300 points per day.
