Installation Instructions
1. Pre-Installation Preparation Tools & Materials:Torque wrench (rated for process flanges) HART communicator (e.g., Rosemount 475) Multimeter, loop calibrator Impulse piping kits (stainless steel tubing, fittings) Electrical cables (shielded twisted pair, 24 AWG minimum).
Safety Checks:Ensure the process loop is depressurized and isolated. Verify compatibility with process media (chemical resistance of wetted parts). Confirm HSE compliance (explosion-proof certifications: ATEX, FM, IECEx).
2. Mounting the Transmitter Positioning:Install on a stable, vibration-free surface. For liquid service: Mount transmitter below impulse lines to prevent gas entrapment. For gas/vapor service: Mount above impulse lines to avoid condensation 14 . Flange Installation:Use Coplanar™ flanges for minimal installation torque. Torque bolts to 15-20 lbf·ft (20-27 N·m) using a crisscross pattern. Ensure flange faces are clean and parallel.
3. Impulse Piping Configuration Piping Guidelines:Use 1/2-14 NPT or DIN 11851 connections. Keep impulse lines short (<3 m) and of equal length for balanced pressure transfer. For high-temperature applications (>121°C), add cooling coils or water seals 14 . Drain/vent Valves:Install drain valves at the lowest point of impulse lines. Use ball valves for easy isolation and maintenance.
4. Calibration & Configuration Zero/Span Adjustment:Apply known pressures to high/low sides. Use HART communicator to set:Zero: 4 mA at 0 pressure. Span: 20 mA at full-scale pressure. Validate with loop testing.
Digital Communication:Configure via HART:Set process variable (PV) to differential pressure. Assign tag names and alarm limits (e.g., high/low pressure alerts).
5. Post-Installation Checks Functional Testing:Verify 4-20 mA output matches applied pressure. Test HART communication with PLC/DCS. Leak Testing:Pressurize impulse lines to 1.5× maximum working pressure. Monitor for leaks at flanges and seals.
6. Safety & Compliance Certifications:ATEX/IECEx Zone 1 (intrinsically safe). FM/CSA Class I, Division 1 (explosion-proof). Documentation:Attach calibration certificates and HART configuration logs. Label transmitter with process tag and safety ratings.
