The Field Instrumentation Technician Supervisor is responsible for overseeing the installation, calibration, testing, troubleshooting, and maintenance of field instrumentation systems. The role ensures that all instruments function reliably and accurately to support safe and efficient plant operations. It involves managing a team of technicians, enforcing safety standards, and coordinating with operations and engineering departments.
Plan and supervise daily instrumentation maintenance tasks including loop checks, instrument calibration, signal testing, and diagnostics.
Allocate work to technicians, monitor progress, and ensure timely task completion.
Ensure adherence to maintenance schedules (PM/CM) and safety protocols.
Oversee installation of field instruments: transmitters (pressure, flow, temperature, level), control valves, analyzers, and switches.
Support commissioning activities including instrument loop checks, I/O mapping, and system integration.
Review P&IDs, loop drawings, and instrument datasheets during installations.
Supervise on-site calibration and testing of field instruments using standard tools (e.g., HART communicators, multimeters, calibrators).
Identify and troubleshoot instrument faults and signal issues affecting plant performance.
Ensure all instruments are calibrated as per schedule and documented accordingly.
Maintain accurate records of maintenance, calibration, and work permits.
Ensure compliance with industry standards (ISA, IEC) and internal procedures.
Participate in audits and ensure test certificates and reports are up to date.
Promote and enforce safety procedures, PPE usage, and lockout/tagout protocols.
Train and mentor junior technicians and help build their troubleshooting capabilities.
Conduct toolbox talks and participate in risk assessments (JSA, HIRA) before tasks.
Strong knowledge of field instrumentation devices and calibration procedures.
Hands-on expertise in using test equipment (HART communicator, Fluke calibrators, etc.).
Familiarity with control systems interfaces (PLC/DCS I/O cards, marshalling panels).
Strong leadership, coordination, and task delegation abilities.
Awareness of ESD systems, SIS loops, and ATEX/IECEx zoning (preferred).
ITI / Diploma in Instrumentation, Electronics, Electrical, or Industrial Automation.
5–10 years of experience in field instrumentation, with at least 2–3 years in a supervisory role.
Experience in oil & gas, chemical, power, or utility industries preferred.
Working knowledge of ISO/IEC standards for instrumentation is an advantage.
