General

Safety Precautions
To prevent possible electrical shock, fire, personal injury or the device damage:

Carefully read user’s manual.
Do not place sensor on the objects which exposed to high voltages.
These voltages could cause personal injury or death.
The Analyzer could not be used in potentially explosive environments.
Take measures to prevent cables and straps become entangled by rotating part of machines at measurement site.
Do not expose PCE-VM 22 parts to heavy impacts, high humidity and extreme temperature.
Do not try to open the display unit – this can damage the system, and your after-sales service warranty will come void.

Overview

The PCE-VM 22 Vibration Analyzer (Device, Analyzer) is a compact yet powerful, vibration analyzer designed to measure overall vibration parameters, FFT spectrum analysis of the rotating machinery, immediate evaluation against ISO 10816 standard, condition monitoring by route based measurements and data collection.
Route files and data files exchange via email makes it ideal for data collection at remote sites. Simple in use, with free firmware upgrades, comes with data management and reporting software.

Measurement functions

Vibration mode: analyzer measures overall level of vibration acceleration, velocity and displacement and FFT spectrum, route or off-route measurements.
Tachometer: analyzer measures speed of rotation by means of contactless optical sensor.
The measurement result is displayed in RPM and Hz.
IR thermometer: contactless measurement of object temperature.
The measurement result is displayed in °C and °F.
