Instrument Technician

Instrumentation & control technicians are responsible for the assembly, installation, removal and replacement,
disassembly, test functionality and operability, maintenance and repair of instrumentation systems and their
associated system components. Such systems can be of an electronic, electro-mechanical or pneumatic
technology which may be used to indicate, record and control a wide variety of equipment, plant and machinery.
An integral aspect of the instrumentation & control technician is the ability to locate and identify faults in a timely
manner to restore plant and equipment to acceptable conditions. The wide range of possible equipment and
systems also require a good knowledge of, and the ability to effectively use, an equally wide range of test and
measuring equipment. Instrumentation & control technicians typically need a good understanding of engineering
theory, the functions of components within systems and the effect on system operation of failure.

Establish and maintain effective working relationships, communicate effectively, and work inclusively to
deliver work within given specifications.

• Demonstrate team working skills and interact with team members in a positive and professional manner.


• Work within an overall risk control strategy which has been developed by safety specialists and includes


detailed criteria for identifying risks, together with clearly defined procedures for action which must be
followed.

• Take personal ownership of, and responsibility for, completing tasks and procedures.


• Follow procedures and relevant codes of standard with integrity and vigour and complete actions and


documents accurately and honestly.

• Take responsibility for identifying and reporting instances where procedures or work instructions cannot be


met or where a variation in them is required.

• Deal promptly and effectively with problems within their control and report those that have been, and those


that cannot be, solved.

• Take responsibility for supervising and mentoring others where appropriate.


• Demonstrate the ability to coordinate work scopes and SIMOPS effectively within a wider team, as required.


• Demonstrate effective handover of responsibility and equipment at the end of a task.


• Take responsibility and ownership of personal development, set targets to plan on how these will be achieved.


• Support operational requirements, achieve targets and maintain records as required, thereby minimising


backlog and downtime.

• Maintain compliance with legislative requirements and company policies, procedures and standards.


• Maintain and demonstrate ongoing technical competence and skill set to current standards and updates.


• Support innovation and development for improvements.


The instrumentation & control technician will:

• Have the required competencies to assemble, install, carry out preventative maintenance, repair, diagnose


faults and remove and replace, and dissemble instrumentation and control systems and their associated
system components.

• Understand the relevant legislative, regulatory and local requirements or procedures and safe working


practices, including their responsibilities with regards to reporting lines and procedures.

• Understand the preparation and reinstatement requirements in respect of the work area, materials and


equipment, and the possible consequences of incorrect actions in these areas.

• Be able to read and interpret relevant engineering drawings, related specifications, quality standards and


equipment manuals, and to follow work instructions and relevant plans and schedules.

• Understand which tools and equipment to use, and when, and will follow relevant training, methods and


techniques and quality control and safety procedures for their use.

• Understand their responsibilities for ensuring the care and security of tools and equipment used.


• Understand the types of defects and testing anomalies that can occur, how to identify them, and what action


to take.

• Diagnose function and test equipment on return to service


• Be able to handle a range of digital information, technology and equipment to support work related tasks and


to communicate information.


• TMI01 - Pressure measurement and control systems - Range check a pressure gauge, change settings on a


pressure switch, recalibrate a SMART pressure transmitter and record Instrument Test Records (ITR's)

• TMI02 - Level measurement and control systems - Reconfigure, calibrate and function check a displacement


type level transmitter and a SMART type level transmitter and record ITRs

• TMI04 - Temperature measurement and control systems - Commission a temperature detector (RTD or


thermocouple) and a SMART temperature transmitter including a range change by a 20% increase or decrease
of its current settings, recalibration and full loop check from heat source to transmitter output, record ITRs.

• TMI14 - Flow measurement and control systems - Recommission a differential pressure flow transmitter into


a fully operational condition, and calibration check the transmitter and record ITRs

• TMI17 - Maintain, calibrate and commission a process control valve - Remove a process control valve


positioner and actuator, replace valve stem gland packing, reassemble and body pressure test. Set up and
stroke test to operate open/closed on a 4-20 mA control signal, complete full loop calibration and record ITRs

• TSBT02 - Disassemble and reinstall SBT assemblies - Identify faults and defects with SBT assemblies,


disassemble SBT assemblies, rectify faults and defects and reinstall SBT assemblies by selecting and using the
correct materials, tools, fittings, clamps and supports in accordance with P&ID and specification sheet
