DYNISCO MODEL MRT460 Multi-Range, Rigid Stem Melt Pressure Transducer Description Now, users can select from among four pressure ranges on one transducer with the new Dynisco MRT, the first multi - range pressure transducer. By simply turning a rotary switch via an access pot on the transducer, four potential pressure ranges can be selected. The transducer can be ordered so that the equivalent psi, bar, Kg/cm2 or MPa ranges can be chosen. This revolutionary melt pressure transducer offers maximum versatility to handle changing process conditions and materials. Features Benefits • Accuracy of better than ±1.0% • Reliable pressure measurement • Four user selectable pressure ranges in one model • Maximizes inventory flexibility • Externally selectable range via rotary switch • Maximum versatility for changing process conditions • 3.33 mV/V FSO for selected range • Standard low level output • Internal 80% shunt calibration • Easy set - up • All stainless steel wetted parts • Corrosion resistant • Proven sensor design • Good stability and repeatability Specifications New Extended Life Coating Performance Characteristics Ranges: psi: 0 - 3,000, 0 - 5,000, 0 - 7,500, 0 - 10,000 bar: 0 - 200, 0 - 350, 0 - 500, 0 - 700 kg/cm2: 0 - 200, 0 - 350, 0 - 500, 0 - 700 MPa: 0 - 20, 0 - 35, 0 - 50, 0 - 70 Accuracy: ±1.0% FSO Repeatability: ±0.10% FSO Mounting torque: 500 inch - lbs. maximum Overload rating: 20,000 psi (1,400 bar) Material in contact with pressure media: 15 - 5 PH stainless steel, Dymax® coated Weight: 1 lb.
