Product Data PROCESS GAUGES XR-Series All-welded Process Gauge and Diaphragm Seal DESCRIPTION The XR-Series all welded system provides users with a leak-proof, tamper-resistant gauge and seal solution that combines the proven durability and performance of our 4-1/2” Model 1981 SOLFRUNT® Process Gauge with our high quality M&G brand Diaphragm Seals. l Best solution for operator safety l Leak-proof – all joints are welded l Petrochemical manufacturing l Oilfield equipment l Chemical manufacturing GAUGE: Model 1981 with 316L SST socket and 316L SST seamless Bourdon tube, or Model 1986 with MONEL socket and MONEL seamless Bourdon tube l Tamper resistant – can’t remove gauge PROCESS CONNECTION: 1/2 NPT male connection standard, other connections available upon request AMETEK USG’s XR models are now available in two versions. Our new Finned Top version has been upgraded to include cooling fins on the body of the seal to improve its cooling features and an optional flushing port. The first generation is still available for customers preferring that design, or applications requiring exotic metals, such as MONEL 400, HASTELLOY, or Tantalum. SEAL ­ ETTED PARTS: 316L stainless steel, MONEL, W HASTELLOY C bodies; 316L stainless steel, MONEL, HASTELLOY C and Tantalum diaphragms; other wetted materials may be available upon request l Seamless bourdon tube gauge standard The XR-Series offers customers a leak-proof, tamperproof, lower cost alternative to an individual gauge and diaphragm seal. The XR-Series increases worker safety by reducing potential leaks in your process by welding 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. The Model 1981 gauges starts with seamless tubing for our bourdon tubes, which provide a seamless solution throughout your process. SEAL FILL FLUID: DC 200 silicone standard; other fills available upon request OPTIONS: Orifice restrictors on gauge; flush port on seal, StaKool™ cooling element, shatter-resistant window on gauge, and capillaries The XR-81 is compliant to NACE MR-01-03 and MR0175 requirements. The designed operating pressure is 3000 psi at 100°F and has a maximum static pressure rating of 5000 psi. The standard XR diaphragm seal has a 4:1 safety ratio and is available in 316l SST, Hastelloy C, MONEL bodies and 316L SST, HASTELLOY, MONEL and Tantalum diaphragms.
