GEFRAN, MELT PRESSURE TRANSDUCERS, MODEL: MD, MELT PRESSURE TRANSMITTERS CAN OPEN digital output The MD series of Gefran, are pressure transmitters for using in High Temperature environment. The main characteristic of this series is the capability to ead temperature of the media up to 400° C. The constructive principle is based on the hydraulic trasmission of the pressure. The fluid-filled system assures the temperature stability. The phisical measure is transformed in a electrical measure by means the strain-gauge technology. MAIN FEATURES Electrical • Digital output signal with DP404 CAN OPEN communication protocol • Transmission frequency ( Baud rate) : 10 Kbaud to 1Mbaud ( default 500 Kbaud) • Software / Hardware selection of Baud rate and ID nodes • Operation with 1 or 2 settable alarm limits • “ Autozero” for temperature compensation • Zero and span drift compensation • 80% FSO calibration signal Mechanical • Pressure ranges: 0-35 to 0-2000 bar / 0-500 to 0-30000 psi • Accuracy: < ± 0.25% FSO ( H) ; < ± 0.5% FSO ( M) • Hydraulic transmission system to guarantee temperature stability.( Hg) • Quantity of Hg contained for model: series MDE0 ( 30mm3) ; MD1, MD2, MD3 ( 40mm3) • Standard threading: 1/ 2-20 UNF, M18x1.5; other versions on request • Autozero function on board / external option • Drift Autocompensation function ( SP version) • Stainless steel 15-5 PH diaphragm with Armoloy coating • For ranges below 100 bar – 1500 psi: stainless steel 17-7PH corrugated diaphragm with GTP coating GTP ( advanced protection) Coating with high resistance against corrosion, abrasion and high temperature
