OMEGA ® Diaphragm Pressure Seals afford greater protection to
sensitive pressure instrumentation from the damaging effects of
corrosives, slurries, or viscous fluids that may be present in your
pressure line. A variety of designs and styles are available to suit your
100 Series Distinguished by its 3-part design, the
100 series includes a PTFE coated diaphragm capsule which threads
into the top housing, assuring positive sealing at all surfaces and
minimizing the possibility of any leakage of the filling fluid from the
system. The diaphragm capsule can be replaced without replacing the
top housing. Continuous duty is assured: should the sensor be removed
from the diaphragm seal, the process fluid is prevented from escaping.
Easy cleaning and inspection of the diaphragm can be achieved during
shutdown conditions by detaching the top and bottom housings. This
design eliminates the need to refill the seal or recalibrate the instrument
when the top and bottom housings are separated. A FKM O-ring,
compatible with all standard fill fluids, and a PTFE back-up ring make a
seal between the diaphragm capsule and the top housing. The
diaphragm is PTFE coated to provide an integral gasket, thus assuring
a leaktight connection between the diaphragm and bottom housing.
The 100 Series consists of a diaphragm capsule with a corrugated,
metallic diaphragm edge welded to a sturdy back-up plate which
threads into the top housing. Once secured, the top housing can be
bolted to the bottom housing. The bottom housing has a standard 1/2
inch NPT fitting which easily threads to the process piping.
102 Series Virtually identical to the 100 Series in both performance and design, the 102 Series includes a standard #150 raised face flange in place of a threaded female NPT process fitting. For more rugged applications, an optional #300 raised face flange is also available.
202 Series The 202 Series diaphragm seal
features a bonded PTFE diaphragm and a PTFE #150 raised face
flange. This all-PTFE wetted construction provides ruggedness and
maximum corrosion resistance to acids, caustics, alkalis, ketones,
hydrocarbons, and alcohols. In the new 202 design, the PTFE
diaphragm is bonded to the top housing, allowing the top housing and
instrument to be removed without losing the fill fluid.
