Spans are fully adjustable up to a 10:1 ratio, providing wide rangeability in a single instrument. Fewer stand- by transmitters are required.
The 11G Series Transmitters use the same topworks as Foxboro Pneumatic d/p Cell Transmitters. This mechanism has been the standard for differential pressure measurement since Foxboro introduced it nearly 50 years ago. Many thousands of successful, trouble-free installations have demonstrated the exceptional dependability of these outstanding transmitters.
These transmitters are equipped with a vernier range adjustment which allows the operator to select one of several predetermined ranges without removing the transmitter from the process. No other calibration apparatus is required for the predetermined ranges.
Since accuracy is a function of calibrated span, precision is retained even with highly elevated- or suppressed-zero ranges.
