IMV VM-5123/6 Vibration measuring

■Features

●Light weight and compact ●6ch input (vibration) + 2ch (Voltage input) ●Available for 3-axis pickup ●Range selector and Low-pass filter is provided ●High S/N ratio ●Waveform data recording and analysis by Note PC(option)

Function

Compact signal conditioner to do optimum processing of signal with connecting servo-type acceleration pickup. It is available for the vibration acceleration measurement with AC voltmeter, waveform observation with oscilloscope and the analysis with FFT analyzer etc. And the voltage signal from sound level meter and microphone etc is possible, and it takes out simultaneously with vibration data. ■Recording function(OPTION) ZERO adjustment, measuring range setting, low pass filter is equipped to do the suitable vibration acceleration measurement. Remote control is possible. Logging setting screen Logging screen ■Analysis function(OPTION) It equips the necessary vibration analysis function as the filter, moving averaging, differential.integral, DC processing in addition to the waveform analysis as statistics analysis, spectrum analysis, mutual spectrum analysis and octave band analysis etc. analysis screen ■Available for many kinds of sensors (OPTION) 2-channel voltage signal (±5V FS) other than servo-type acceleration pickup can be inputted. The output from sound level meter, manometer, thermometer other than vibration can be inputted. analysis screen
