The Series PTGA and PTGC Differential PressurePiston-Type Gages can be used tomeasure the pressure drop across filters, strainers, pump performance testing,and heat exchanger pressure drop monitoring. Its simple, rugged designpossesses a weather and corrosion resistant gage front with a shatterresistant lens. The Series PTGA and PTGC contain a piston-sensing element,which provides differential pressure ranges from 0-10 psid through 0-400 psid.Constructed from aluminum or 316 Stainless Steel and available with two1/4″ female NPT end connections, the gages provides over range protectionrated to 5000 psig (340 bar).Service:Compatible gases and liquids.Wetted Materials: Gage Body: Aluminum or316 SS; Piston: 316 SS; Spring: 316 SS; Ceramic Magnet; End Plugs: Aluminum(Aluminum Body), 316 SS (SS Body); Seals: Buna-N (standard).Dial Case: “Engineered Plastic”with shatter-resistant acrylic lens.Accuracy: PTGA: ±3-2-3% of full scale inaccordance with ASME B40.100 Grade B; PTGC: ±5% of full scale ascending.Pressure Limits: Working pressure 5000 psig(340 bar); Proof Pressure 10,000 psig (689 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.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
