The top graph shows the filtered process variable as seen on the DCS. The middle graph shows the process variable as seen on the 3051S pressure transmitter. The bottom graph shows the standard deviation as calculated in the pressure transmitter. In the middle graph, the left 1/3 is a normal process. The middle 1/3 shows the noise when one impulse leg plugs. The right 1/3 shows the noise when both impulse legs are plugged.
