The Foxboro Model 11GM Transmitters accurately measure gauge pressure and transmit a proportional pneumatic output signal to receivers which may be several hundred meters or yards away. Spans are fully adjustable up to a 10:1 ratio, providing wide rangeability in a single instrument. Fewer stand-by transmitters are required. Since accuracy is a function of calibrated span, precision is retained even with highly elevated- or suppressed-zero ranges.
