The Series PTGB Differential PressurePiston-Type Gage is a low cost differential pressure gage used to measurethe pressure drop across filters, strainers, pump performance testing, andheat exchanger pressure drop monitoring. Its simple, rugged and compact designpossesses a weather and corrosion resistant gage front with a shatterresistant lens. The Series PTGB contains a piston-sensing element, whichprovides differential pressure ranges from 0-10 psid to 0-110 psid withaccuracies of ±3-2-3%. Constructed from aluminum or 316 stainless steel andavailable with two 1/4″ female NPT back or end connections, the SeriesPTGB is cost-effective and accurate in monitoring differential pressure.Service:Compatible gases and liquids.Wetted Materials: Gage body: Aluminum or316L SS; Piston: 316 SS; Spring: 316 SS; Ceramic Magnet; End Plugs: Aluminum(Aluminum Body), 316L SS (SS Body); Seals: Buna-N (standard).Dial Case: “Engineered Plastic”with shatter-resistant acrylic lens.Accuracy: ±3-2-3% of full scale inaccordance with ASME B40.100 Grade B.Pressure Limits: Working pressure 6000 psig(400 bar); Proof Pressure 12,000 psig (827 bar).Temperature Limits: -40 to 200°F (-40 to93°C).Size: 2.5″ (63 mm) or 4.5″ (115mm).Mounting Orientation: Mount in anyposition.Process Connections: 1/4″ female NPTend connections standard; 1/4″ female NPT back connections optional.Weight: Aluminum: 2.5″: 0.60 lb (0.27kg), 4.5″: 0.95 lb (0.43 kg); 316 SS: 2.5″: 1.35 lb (0.61 kg),4.5″: 1.60 lb (0.73 kg).
