Spans are adjustable as much as 10 to 1 for broad rangeability in a single instrument. Fewer stand-by transmitters are required.
The 11A Series Transmitter uses the same topworks as a Foxboro pneumatic d/p Cell. This mechanism, introduced by Foxboro over 30 years ago, is the standard of process industries for differential pressure measurement. Many thousands of successful, trouble-free installations demonstrate the exceptional dependability of these outstanding instruments.
Equipped with a vernier range adjustment, 11A Series Transmitters allow an operator to select one of several predetermined ranges without removing the instrument from the process. No other calibration apparatus is required for the predetermined ranges.
