DYNISCO MODEL EPR3 Enhanced Push-Rod Design Melt Pressure Transducer Description Dynisco’s model EPR3 high - temperature melt pressure transducer is offered as an alternative to its PT420 and PT460 series. The push - rod design is suitable for applications where the use of a filled system may not be desirable, such as the extrusion of food and medical products and the manufacture of photographic film. Model EPR3 is available in pressure ranges from 0 - 1,500 through 0 - 10,000 psi. Features Benefits • • • • • • • • • • Better than ±0.5% accuracy Push - rod design Measures up to 750˚F (400˚C) All stainless steel, wetted parts Internal 80% shunt calibration Reliable pressure measurement Ideal for medical, food and photographic film extrusion Ideal for high temperature processes Corrosion resistant Easy set - up Specifications New Extended Life Coating Performance Characteristics Ranges (psi): 0 - 1,500, 0 - 3,000, 0 - 5,000, 0 - 7,500, 0 - 10,000 Accuracy: ±0.5% FSO Repeatability: ±0.2% FSO Mounting torque: 100 inch - lbs. recommended, 250 inch - lbs. maximum Maximum pressure: 150% full scale Material in contact with pressure media: 17 - 4 PH stainless steel, Dymax® coated Weight: 13.25 oz.
