Installation Instructions
1. Installation Location
Avoid excessive vibration, temp extremes, and direct sunlight.
Mount vertically (process connection downward) to prevent condensate accumulation.
Ensure easy access for calibration/maintenance.
2. Process Connection
Use compatible flanges/gaskets per process media (check material specs).
Torque flange bolts evenly to manufacturer specs (avoid over-tightening).
Isolate from line shock using valves/pulsation dampeners.
3. Electrical Connections
Power supply: 10.5-42 V DC (loop-powered).
Polarity: "+" to terminal 1, "-" to terminal 2.
Use shielded twisted-pair cable; ground shield at one end (DCS/PLC side).
Ensure conduit seals for hazardous areas (Ex certifications).
4. Commissioning
Zero calibration: Vent both ports (for gauge/differential models) and adjust via local button/HART.
Span calibration: Apply known pressure and trim using HART communicator (375/475).
Verify 4-20 mA output correlates with applied pressure.
5. Configuration
Set range (URL/LRL) via HART.
Configure units (psi, bar, etc.), damping, and failure mode (upscale/downscale).
Enable diagnostics (sensor/electronics health).
6. Safety & Maintenance
Isolate process pressure before servicing.
Inspect seals/gaskets annually; replace if corroded/worn.
Recalibrate every 12-24 months or per process criticality.
Key Notes
Avoid overpressure: Check max pressure rating vs. process.
Use compatible wetted materials for corrosive media.
Ensure proper grounding to prevent EMI/noise.
