The VM120 Vibration Meter is a poortable instrument, which is battery powered. To make a vibration measurement, an external sensor is required to provide a signal proportional to the acceleration value.
Both RMS and Peak-Peak measurements can be made of acceleration, velocity and displacement.
Three decade ranges are also provided for maximum resolution together with low pass filter for the reduction of wide band noise.
An AC output is provided via the D type output socket. This allows the connection of filter sets, Fourier analysers, etc. for further signal analysis. A DC output is provided to drive chart recorders etc.
