USG AMETEK XR All-Welded Pressure Gauge and Diaphragm Seal
The AMETEK® XR All-Welded Pressure Gauge and Diaphragm Seal was built to avoid the leak issues inherent in standard threaded pressure gauge and diaphragm seal arrangements. The XR-Series features a model 1981 pressure gauge welded to an XR diaphragm seal, with the seal also welded to the pressure gauge’s socket. Additionally, all internal elements of the diaphragm seal are welded together.
Various models are comprised of the following:
- XR-81: all 316L, with a 1981 Solid Front Process Gauge
- XR-86: all Monel®, with a 1986 gauge
The XR-Series is offered with either a 4 or 4-1/2-inch gauge. A 4-inch model 656 stainless steel gauge or a Hastelloy C diaphragm seal are additional options with the XR seal.
