Accelerometer PCE-VM 20-ICA incl. ISO Calibration Certificate

The accelerometer PCE-VM 20 is a compact device for the direct evaluation of the vibration behavior of a machine. The device can measure and display various vibration parameters, such as vibration acceleration, vibration velocity or vibration displacement. Thanks to the integrated real-time FFT analysis, the condition of a machine can be analyzed and determined during the measurement.

The PCE-VM 20 vibration meter can evaluate and display signals from IEPE standard piezoelectric vibration sensors as well as piezoelectric vibration sensors with charge output.
