OMEGA Engineering, Inc. Diaphragm Pressure Seal

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 application requirements. 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.
