The Beran 766 Portable is a fully integrated, single instrument developed from the Beran 766 Condition Monitoring System. It is designed for use by vibration analysts in trouble shooting, balancing and return-to-service/commissioning roles. The unit does not require a PC to operate, ensuring it may be left on to log on-site without the normal security concerns associated with leaving lap-top PCs unattended. Time and RPM based logging may be enabled ensuring Run-up, Coast Down and On-Line Plant operational modes are automatically stored.

Using the latest data compression technology, full real-time graphical capability is available over a modem link. This allows a 766 Portable to be left on-site, but monitored by Vibration Analysts at a remote location – anywhere in the world! The unit is fully controllable remotely to allow alarm settings or logging rates etc., to be adjusted via a modem.
