  • PCE Instruments VM 20 Vibration Meter 0.5 to 15,000 Hz

    # VM 20

    • The vibration measuring device 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.
