The Moving Analog Indicator displays an analog value in context with other information about that value so that you can visually and quickly see if the value is in the normal range or not. The current value is shown as an arrow pointing at a bar with segments showing the desired operating range, low and high alarm ranges, and interlock ranges.
The Moving Analog Indicator component allows for extremely fast information delivery. At a glance, it is obvious to an operator whether or not the value is where it should be, or if it needs attention. If the value is in one of its alarm ranges, then that range can be set to change color to get attention.
