The balancer/analyzer for fixed-wing or rotorcraft

Whether you have a fixed-wing aircraft, helicopter, turbine engine or reciprocating engine, there's a Vibrex™ 2000 to meet your needs.

The Vibrex™ 2000 is a vibration analysis and balancing tool that rapidly and accurately acquires and analyzes aircraft and engine vibration data. It uses that data to calculate balance solutions and to analyze aircraft vibration levels across a broad frequency range.

The balancer/analyzer acquires accurate propeller and helicopter vibration readings. The Vibrex™ 2000 will balance propellers without the need of a chart or use one of the 150 available Chadwick paper charts, or factory charts, to balance your helicopter. Also capable of balancing shafts and blowers, the Vibrex™ 2000 is a complete balancing tool.

As a spectrum analyzer, it provides the operator with an overview of rotor and drivetrain vibration.

3 models to fit your needs

Vibrex 2000
The basic Vibrex™ 2000 is applicable to aircraft and engines with component frequencies of 20,000 rpm or less and balance speeds below 10,000 rpm. For recip powered aircraft the Vibrex™ 2000 basic model is a sure fit.

Vibrex 2000 Plus
For applications where there is a need to perform higher frequency spectrum analysis, such as a turbine engine, the Vibrex™ 2000 Plus measures to 600,000 rpm.

The Vibrex™ 2000 Plus model also adds a spectrum viewer for on-screen graphical display of spectral data.

Enhanced Vibrex 2000 Plus
The new EV2K+ has all the features of the V2K+, in addition to supporting the Fastrak optical tracker for hands-free main rotor blade tracking. EV2K+ also supports the 135M-12 Strobex for those who prefer visual feedback.

All models, no matter the application, provide easy-to-use features that assist the maintainer in decreasing maintenance time, lowering maintenance costs and increasing aircraft availability.

4 easy steps to FAA-approved prop balance

Easy to understand menus allow the user to initiate and complete up to 4 different balancing jobs at one time. The instrument will automatically correct for the propeller response to weight changes and this correction can be saved for future balancing exercises.




A "first round hit" solution means less vibration, even on the first adjustment. Two channels allow the user to measure the propeller and rear of the engine during balancing.

All measurements, sensitivities, solutions, and annotations are stored in memory and can be reviewed on the instrument, printed on the optional portable thermal printer, or downloaded to a personal computer.

Use the Vibrex™ 2000 along with Chadwick's FAA-approved "The Smooth Propeller" publication to lower vibration and improve ride quality.




Customized Kits Available

The Vibrex™ 2000 product line comes as a complete kit, with all the software, accessories, and instructions for your particular application in a rugged, portable carrying case.

With over 45 years of experience on more that 300 different applications, Chadwick products are proven and reliable.

Pinpoint problem components

Spectrum Analysis
Use the Vibrex™ 2000 spectrum feature to pinpoint problem components with ease. The "List Peaks" spectrum printout identifies the highest peaks quickly. Use the harmonic and order features to identify misalignment, mechanical looseness, or imbalance to guide your maintenance action.

An added feature of the Vibrex 2000 Plus model is a simple yet sophisticated spectrum viewer.
