The Vibration Analyzer is a digital signal controller based system which is used to analyze the vibration signals arising out of a rotating machine and records the required parameters. The vibration analyzer computes the amplitude and phase of each input signal simultaneously with reference to the tracking input. The instrument has the features like DC level, overall vibration and tracking filtered measurements. The instrument shall measure the frequency, acceleration/deceleration rate of this tracking signal and communicate the same to PC and also operate as a relay whenever the signal level exceeds certain limit which is set through PC. All the parameters are available on RS-485 network with MODBUS format.
