2.2.1 Vibrex 2000 System Overview
The Vibrex 2000 unit is a hand-held, battery-powered vibration analyzer.
It is a vibration analysis and balancing tool that rapidly and accurately
acquires and analyzes aircraft vibration data. It uses that data to calculate
balance solutions and to analyze aircraft vibration levels across a broad
frequency range.
The Vibrex 2000 system provides accurate helicopter vibration readings
for chart calculations on main and tail rotors, shafts, and blowers. As a
spectrum analyzer, they provide the operator with an overview of rotor
and drive-train vibration. The Vibrex unit uses the cables and transducers
(for example, the Chadwick-Helmuth Model 7310 Velocimeter, magnetic
pickups, and photocells) from previous generations of our equipment,
further reducing the cost of ownership.
