Bailey 820 Line of controller cards, 6624505E1 Square Root.
The Bailey part number 6624505E1 refers to a Square Root Extractor Module designed specifically for the legacy Bailey ICS 820 control system (later acquired by ABB).
- Function: A square root extractor is used in industrial instrumentation to linearize signals from differential pressure (Delta P) transmitters. Because flow rates in a pipeline are proportional to the square root of the differential pressure, this hardware card extracts the square root of the incoming electronic signal to output a true, linear representation of flow.
