FWD Reference Calibration System

落锤式弯沉仪参考标定系统

An FWD is only as good as its last calibration, and road agencies running several units need a common reference. This system checks the load cell against a 0–250 kN reference cell at ±0.3% and the geophones against an LVDT with 0.1 µm resolution. Software calculates calibration factors and prints certificates.
