IMI SENSORS' Series 684 indicator alarm module provides an economical solution to machine shutdown protection when increased vibration levels signify potential failure. The modules, available in various sizes, include up to eight channels in a single NEMA 4X enclosure. Each meter has the ability to integrate an accelerated signal and display the units in acceleration, velocity, or displacement on the highly visible, bright display. The raw vibration signal can be accessed via BNC connections on the front of the module for easy interface with data collection equipment.
