Product Parameters
1. Safety PrecautionsHazard Awareness: Verify that the installation area is free from explosive gases, corrosive chemicals, excessive vibration, or electromagnetic interference from high-power equipment.
Power Disconnection: Isolate power sources and lock out/tag out (LOTO) circuits before performing wiring or mechanical adjustments. Confirm zero energy state using a multimeter.
Personal Protective Equipment (PPE): Wear ANSI-approved safety glasses, chemical-resistant gloves, steel-toe boots, and flame-retardant clothing in hazardous areas.
Compliance: Adhere to regional regulations including NEC Section 501 for Class I Div. 1/2, ATEX Directive 2014/34/EU, and IECEx IEC 60079-0 for explosive atmospheres.
2. Unpacking and InspectionVisually inspect shipping container for impact marks, water damage, or tampering. Photograph any irregularities for claim documentation.
Cross-check the model number2090PG, suffix codes (e.g., S for stainless steel flange), and serial number against purchase documents.
Inventory components: transmitter assembly, 316L SST mounting bolts (M6×20mm) and IECEx/ATEX certification leaflets.
3. Mounting RequirementsLocation: Select areas with ambient humidity <85% non-condensing and altitude <2000m ASL. Maintain 50mm clearance around housing for heat dissipation.
Orientation: For liquid service, position the electronics head ±5° from vertical to prevent air entrapment in the sensing diaphragm.
Process Connection: Match flange ratings (ANSI 150#/300#) to pipeline specifications. Apply anti-seize compound (e.g., Loctite 771) on tapered threads for corrosion resistance.
Support: Install on 50×50mm DIN rail (P/N 00925-0300-0001) or use dual M8 bolts on flat surfaces. Apply 25 Nm torque for bracket fixation.
4. Electrical ConnectionsTerminal Access: Insert a 3mm Allen key into the cover's tension screws and rotate counterclockwise. Verify IP66 seal integrity post-reassembly.
Wiring:
Route 18 AWG shielded cables through ½" NPT cable glands with IP68-rated stuffing boxes. Maintain 100mm service loops near terminals.
For intrinsic safety (IS) installations, use blue IS barriers (e.g., MTL5041) with entity parameters: Ui=28V, Ii=93mA, Pi=0.65W.
Ground terminal (marked ) must bond to facility's equipotential grid using ≤10Ω impedance path.
Conduit Sealing: In Division 1 zones, install UL-listed explosion-proof unions (e.g., Crouse-Hinds CDS) with Xypex™ sealant putty.
5. Process Connection InstallationIsolation Valve: Install 3-way ball valves (e.g., Swagelok SS-43GXS6) with bleed ports for live zero calibration.
Impulse Piping:
For high-temperature (>180°C) steam, use capillary seal assemblies (P/N 00925-0200-1002) with 10mm OD 316L SST tubing.
In slurry applications, install chemical diaphragm seals (P/N 00809-0050-2003) and fill with Halocarbon® 27-X grease.
Slope impulse lines at 1:12 gradient. Support pipes every 1.5m using cushioned clamps.
Sealing: Wrap male threads clockwise with 3 layers of ½" wide PTFE tape. Torque flange unions incrementally using a cross-pattern sequence.
6. Zero CalibrationPreconditions: Equalize process and atmospheric pressure via vent valves. Allow 30-minute thermal stabilization at 25±3°C.
Procedure:
Activate the ZERO function via the local interface button (hold 3s until LED flashes green).
For HART® 7 calibration: Connect a HART475 communicator, navigate to Online > Trim > Sensor Trim > Zero Trim, and confirm offset within ±0.025% FS.
7. Configuration and TestingRange Setting: Using the magnetic SPAN adjuster, align the upper range limit (URL) with the 20mA output. For example: 0-10 bar → 4mA=0 bar, 20mA=10 bar.
Leak Test: Pressurize to 1.5× URL for 15 minutes. Acceptable leakage rate: <0.1% FS/hr measured by pressure decay.
Output Verification: Inject 0%, 50%, and 100% pressures via deadweight tester. Record mA readings with a 0.05% precision multimeter. Tolerance: ±0.075% of span.
8. Final InspectionVerify torque values: process flange (45 Nm), cable glands (12 Nm), and housing screws (0.7 Nm).
Affix laser-etched nameplates with SIL 3 rating data: PFDAvg=0.0001, SFF=99.9%, HFT=1.
Perform 3-point linearity check using AMETEK DPI 620 pressure calibrator.
9. MaintenanceQuarterly Checks: Measure insulation resistance (>100MΩ at 500VDC) between terminals and ground.
Biennial Service: Replace O-rings using Emerson-approved FKM material (P/N 00809-0100-4002). Lubricate stem with Dow Corning® 55 grease.
Diaphragm Integrity Test: Apply 110% overpressure for 5 minutes. Output drift must remain <0.1% FS after pressure release.
