FFT Vibration Analyzer And Balancer


FFT Vibration Analyzer And Balancer- BALTECH VP-3470

The new system BALTECH VP-3470 is a modification of the previous portable balancing devices. The main reason of increased vibration of rotating machines is unbalance which results in bearing failure. The unbalance leads to premature bearing failure, oil degradation, increased noise level, shaft damage, and equipment performance degradation. The unbalance correction is quite a hard task which should be performed by a skilled staff using complex measurement equipment. The new multifunctional system BALTECH VP-3470 makes the dynamic balancing easier and simpler. The system is designed for use by service and repair specialists, mechanics, and power engineers.

The portable balancing system can be used not only for balancing of fans, exhausters, cooling towers but also as a measuring unit for balancing machines. The BALTECH VP-3470 system consists of all the instruments required for fast and efficient field balancing. BALTECH VP-3470 includes electronic angle gauge for minimization of balancing runs and precise installation of balancing mass; balancing scales, test weights and the BALTECH Expert software for reporting.

The BALTECH VP-3470 vibration testing was designed specifically for maintenance professionals who need to quickly perform vibration analysis and evaluate alignment to understand the root cause of equipment condition. Vibration Analyzer can carry out the demanding task regardless of the technical problem at hand. BALTECH VP-3470 is a lightweight portable two-channel digital data collector, which is designed to measure vibration, analyze vibration parameters and to perform a dynamic balancing in own bearings. This portable device is intended to conduct a periodic vibration monitoring and setup of power and mechanical equipment.
