Emerson MMS 677X Dual Channel Bar Chart Indicator

Emerson MMS 677X Dual Channel Bar Chart Indicator

Equipment Overview

The MMS 677X series dual channel bar chart indicator (including MMS 6771 and MMS 6772) belongs to the MMS 6000 series machine monitoring system and is used to display the measurement results of the MMS 6000 module. With a dual channel design, the MMS 6000 monitor can display data from two channels simultaneously. The bar chart resolution is 100 scale lines, corresponding to a range of 0... 100% or ± 50%, and can present measurement results at a resolution of 1%. It adopts a 19 inch design.
