Selecting the Proper Diaphragm Seal
Diaphragm seals are used in many industries to isolate pressure measurement devices
from the process media for different reasons. It could be to protect the sensing elements
of a pressure gauge from a corrosive fluid, or to prevent particles from a pulp
slurry from clogging a bourdon tube in a pressure gauge. Or, maybe the fluid temperature
is too hot to come into direct contact with a transmitter. Alternatively, perhaps the
process fluid needs to be protected from the gauge, especially crucial in the food and
beverage industry with CIP/SIP requirements.
Because there are so many applications for diaphragm seals, many variables exist that
must be considered. These can include process media type, pressure ranges, materials,
size, fill fluids, and instrument connection size, to name a few. To make things more
complicated, some of these options are not compatible with each other. These variables
make choosing the correct diaphragm seal difficult!
Our Solution
AMETEK U.S. Gauge has an easy-to-use solution that makes selecting the correct
diaphragm seal a task that takes minutes rather than hours. Our webstore includes a
system of dynamically updating menus that only show you the options available with
each selection you make. The result is a complete part number and price for the choices
you have selected.
Once a seal is selected, you can then decide if you want us to mount a pressure gauge
on the seal for you. Similar to the dynamically updated menus, our website will only
show you pressure gauges that are compatible with the particular seal you have designed.
Choose the desired gauge, press order, and wait for the mounted gauge/seal
combination to arrive.
The system also works in reverse. If you would like to choose the gauge first, we will then
show you the diaphragm seal options that are compatible with your selected gauge.
Visit our webstore at webshop.ametekusg.com to customize your seal and gauge
combination today.
