The PCE-VM 25 Vibration Meter is designed for engine monitoring to assure a smooth operation of machines. Due to its simple application, the Vibration Meter can be used for the measurement of a large range of parameters including acceleration, velocity and displacement. The Vibration Meter not only shows the effective value but also the peak value and crest factor. The Vibration Meter delivers detailed information on the current state as well as past history of the measurement values due to a spectral analysis and a tendency prognosis. Measured data can be transferred to a computer via a USB connection in order to evaluate it there in an optionally purchasable software. This allows long-term measurements to be recorded and reviewed in detail. Even if the data is not transferred, the Vibration Meter has enough data storage capacity to save 16,000 measured values internally. There is also the option of purchasing VMID measurement slots.

General Information on VMID-measurement locations
There can be optionally VMID measuring point used for the analysis. These are magnetic coupling parts made of stainless steel, that have a digital serial number. This serial number can be transferred through a read-out contact inside the sensor's bottom via the sensor cable. By using these fixed measuring points it is guaranteed that the relevant locations can be measured again and again.
