Improving the cooling properties of pressure gauges and diaphragm seal combos, AMETEK US Gauge® has added a finned-top model to its XR Series of all-welded process gauges and diaphragm seals.

The added feature improves the cooling capabilities of the integrated pressure gauge and diaphragm seal, with the finned design reducing process temperatures from 225ºF to 160ºF.

The new finned-top XR Series process gauge combines the proven safety, durability and performance of a high-quality SOLFRUNT® 1981 pressure gauge with an AMETEK M&G diaphragm seal in an all-welded gauge-to-seal design that offers customers a leak-proof, tamper-proof, lower-cost alternative to an individual gauge and diaphragm seal.

Also included on the new version is an optional flushing port. 

The USG Model 1981 pressure gauge also features 316L stainless steel internals and a seamless Bourdon tube standard ensuring superior burst or rupture pressure performance.  The pressure gauge is welded to an M&G 316L stainless steel diaphragm seal with ½-inch NPT process connection. 

The finned-top XR-81 is compliant with NACE MR-01-03 and MR-0175 requirements and has a designed operating pressure of 3000 psi at 100ºF and a maximum static pressure rating of 5000 psi.

Along with the XR-81, AMETEK offers the XR-86, which is made with a USG Model 1986 gauge (MONEL® internals) welded to an M&G MONEL® diaphragm seal. Both the XR-81 and XR-86 all-welded gauges offer superior performance in corrosive and hazardous media applications than stand alone gauges, AMETEK explains.
