Accelerometer PCE-VM 20
Vibration measuring device for vibration measurement on machines / Direct evaluation according to DIN ISO 10816 / Various measurement modes / Real-time FFT analysis / Route option for fast acquisition of measuring points
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.
