MF-PD md-1323gb / 2008-10-21 Application MF-PD is a pressure transmitter designed for measuring of low positive, negative and differential pressure.  Output signal in Volt and mA  Simple One-Key zero-setting  Two selectable measuring ranges, full range or half range  Selectable damping  Calibration certificate attached  Negative or Positive indication of pressure Pressure connections Pressure connections should be made with Micatrone mounting kits for safe and tight function. Connect the measurement outputs with HT-plastic tube 8/6 mm. Display unit MF-PD is fitted with a 4-digit LED display and minus [-] sign when indicating negative pressure. Zero adjustment Press down the "zero-setting"-button until the LED turns off. Release the button and the zero-setting is finished. Output signal setting The Volt/mA-output signal has different terminals. Check that the correct output is connected. Setting of damping The MF-PD offers a possibility to set different damping (time constant). At delivery the damping is set to 1,50 seconds damping. Half measuring range Through a miniature switch the measuring range can be set to full range (100%) or to half measuring range (50%). NOTE! The accuracy is always for the full range. Adjusting the measuring range The measuring range can be adjusted to correct a measuring deviation. Instruction can be found on our web site, www.micatrone.se. Programming Micaflex PD is programmable with 4 keys on the display unit and include programmable parameters for the alarm function and negative indication. Alarm function MF-PD include a visual alarm indicated by a flashing display on alarm state if this function is activated. By using an optional plug-in module, a potential-free changing relay output can be obtained. Alarm can be set for High or Low pressure. A time delay can be set for 0...600 seconds. © AB MICATRONE 2008-10-21 [h: \ appdok \ typeset \ datablad \ md-1323gb_081021.vp] MicaFlex Microcontroller-based Differential pressure transmitter with digital indication catrone® Product data sheet TG1 T2 LED1 R40 J1 PL1 IC8 C5 R39 K2 INC DIL1 AC7A C14 R8 R35 J2 R12 C12 IC6 IC3 AC3 C10 C23 R17 R38 ZERO IC1 R33 R14 PL2 R34 IC2 R42 DEC C9 R41 R15 VDR1 R24 K1 R44 R16 K3 D1 C4 R2 K4 R46 IC7 AC9 R37 R11 D2 R32 R21 R31 R7 R47 R23 IC9 T1 AC1 R10 C7 R19 C3 C1 C6 R1 R43 C15 C11 T3 C16 R9 R13 R29 R6 R20 R4 D3 AC8 R25 R45 R30 RGND C17 IC4 R27 R26 R28 C13 R36 R22 R48 C20 IC5 AC2 C22 R5 C24 D5 C19 D7 C21 R18 D6 C18 C8 C2 D4 AC7D FM1 FM2 FM3 TEST (-) 2 3 4 Out mA G0 (+) G0 RANGE 1 G (-) DIL1 5 Out V ZERO * 5 DAMPING DAMPING see cover 4 3 OUTPUT * AB Micatrone P3778 v3.01 Top Silk 2 1 R110 D103 DIG4 IC101 RP101 H2 R101 LED101 LED102 R112 D101 LED103 C101 C102 SW4 SW3 SW2 SW1 R109 R111 RP102 D104 D102 LED105 D105 J101 R102 H1 FM2 FM3 K101 DIG1 DIG2 DIG3 LED104 SNAP1 FM1 AB Micatrone P3761 Top Silk PGM ESC 8 8 8 8 Zero-setting button miniature switch Adjustment keys .
