The Mid-Level Field Instrumentation Technician is responsible for performing routine maintenance, calibration, installation, and troubleshooting of various field instrumentation devices. The role supports plant reliability by ensuring that all field instruments operate within required specifications and standards. This position requires strong hands-on skills, adherence to safety protocols, and the ability to work independently or as part of a team.
Perform preventive and corrective maintenance of pressure, flow, temperature, level instruments, and analyzers.
Carry out field calibration and adjustments using standard equipment (e.g., HART communicator, calibrators).
Ensure all instruments are maintained in compliance with calibration schedules and regulatory standards.
Assist in the installation and commissioning of field instruments.
Conduct loop checks from the field to DCS/PLC during system commissioning or modifications.
Verify signal integrity and proper functionality of transmitters, switches, and control valves.
Identify and rectify faults in instrument loops (e.g., signal failure, wiring issues, erratic readings).
Replace or repair faulty transmitters, sensors, cables, and junction boxes as needed.
Support during breakdowns or shutdown activities to restore instrumentation quickly.
Follow plant safety practices, PPE requirements, and work permit systems.
Ensure work complies with relevant standards (e.g., ISA, IEC, ATEX).
Participate in toolbox talks, risk assessments, and job safety analysis (JSA).
Maintain records of completed work, calibration results, and instrument history.
Update as-built loop files, panel drawings, and instrument tag lists as required.
Report instrument anomalies to supervisors or engineers for further action.
Practical knowledge of common field instruments (pressure, flow, temperature, level).
Ability to use calibration tools and troubleshooting devices (e.g., multimeter, communicator).
Understanding of instrument wiring, loop diagrams, and basic control system interfaces.
Good communication, teamwork, and time management skills.
Awareness of intrinsically safe (IS) and explosion-proof (Ex) standards is a plus.
ITI or Diploma in Instrumentation, Electronics, or Electrical Engineering.
3–7 years of relevant field instrumentation experience.
Experience in process plants such as oil & gas, chemicals, water treatment, or power generation.
Familiarity with DCS/PLC systems, control panel wiring, and field termination.
