- Series GGM
Plast-O-Matic Gauge Guards have been providing protection for gauges and
pressure instruments for over 20 years. This field proven product offers a choice
of VitonŽ or TeflonŽ diaphragms. The VitonŽ diaphragm can be used for vacuum
applications to 30"Hg. and like the Teflon diaphragm can be supplied with gauges up
to 200 PSI. The large surface area of the diaphragm allows accurate transmission of
solution pressure to the gauge with some tolerance for air bubbles within the gauge.
The diaphragm is strong -- and would not blow out even if the gauge were to be
removed. It is suggested that the diaphragm be replaced if this were to occur.
A removable upper housing is available if cleaning of the process side of the diaphragm is
required -- the gauge and fill solution remain undisturbed. Optional gauge shields
are available to protect the gauge from the external environmental corrosion. The
clear acrylic shield can be used with top and back mounted gauges. For extreme
vibration or pulsation applications, a snubber insert is also available as an
option. The gauge connection uses a O-ring seal -- this prevents the need to over
tighten the gauge into guard. Standard gauge connections are 1/4" FNPT with an
option of 1/2" FNPT -- the process connection is 1/2" FNPT.
