The XR-Series starts with a Model 1981 process gauge and welds that to a XR diaphragm seal. All the components of the diaphragm seal are welded together internally and the seal is welded to the socket of the pressure gauge. This eliminates any leak paths traditionally found in a threaded pressure gauge and diaphragm seal combination.
The XR-81 is an all 316L model with a 1981 Solid Front Process Gauge, and the XR-86 is an all Monel combination with a 1986 gauge. The XR seal is also available with a Hastelloy C diaphragm seal, or with a 4” Model 656 stainless steel gauge.
Best solution for operator safety
Leak-proof – all joints are welded
Seamless bourdon tube gauge standard
Tamper resistant – can’t remove gauge
4:1 safety ratio
AMETEK USG’s XR models are now available in two versions. Our new Finned Top version has been upgrad-ed to include cooling fins on the body of the seal to im-prove its cooling features and an optional flushing port. The first generation is still available for customers prefer-ring that design, or applications requiring exotic metals, such as MONEL 400, HASTELLOY, or Tantalum.
The XR-Series offers customers a leak-proof, tamper-proof, lower cost alternative to an individual gauge and diaphragm seal. The XR-Series increases worker safety by reducing potential leaks in your process by weld-ing the gauge to the seal and including our Model 1981 process gauge with a seamless bourdon tube. Many companies specify seamless tubing throughout their plants for their process lines, yet they use gauges that have welded tubing.
