Field Instrumentation:

• Install, calibrate, and maintain a variety of field instruments, including:
• Pressure Sensors
• Differential Pressure Sensors
• Level Transmitters
• Temperature Sensors (RTD/thermocouples)
• H₂S Gas Detectors
• Combustible Gas Detectors (LEL)
• leak detection sensors
• Ensure proper grounding, shielding, and wiring of instrumentation in hazardous zones.

Preventive & Corrective Maintenance:

• Conduct regular instrument calibration using field calibrators.
• Troubleshoot signal losses, noisy readings, or device failures.
• Replace or reconfigure field devices in response to alarms or performance issues.

Data Integrity & Communication:

• Verify SCADA signal integrity from sensor to control room interface.
• Maintain real-time data availability for operations, safety, and reporting systems.

Documentation & Reporting:

• Update wiring diagrams, I/O maps, and tag lists as needed.
• Document calibration certificates and maintenance records.
• Provide detailed field reports for any faults, repairs, or configuration changes.

Coordination & Safety:
