655 Vibration Meter, Analyzer and Balancer Kit
The Vitec Model 655 Compact Balance Analyzer is used for in-place balancing, vibration measurement and stop-motion analysis of rotating machinery. Its color-coded front panel controls and 6.5 lb. weight make it an easy-to-use field instrument. A single switch selects one of four modes of operation: the Meter mode allows the operator to measure the overall level of vibration in displacement or velocity; the Strobe mode offers user-selectable strobe firing rates for stop-motion analysis; an Analyze mode allows the Model 655 to be tuned to specific frequencies for signature analysis. Balancing is accomplished in the phase mode. The tunable filter is based on a programmable digital LSI chip to give a high degree of accuracy and drift-free readings.
Although light in weight and small in size, the Model 655 offers features found normally only on larger, more expensive analyzers. An AC output jack can be used to view the incoming signal on an oscilloscope. An X/Y recorder output is provided for hard copy signature analysis purposes. Dual switch-selectable pickup inputs make two-plane balancing operations easier. All vibration readings are based on a true RMS circuit to provide the most accurate vibration indications possible.
The Model 655 will operate for up to 40 hours on a single charge in the meter or analyzer mode and up to one hour in the strobe/balance mode.
