Instrumentation
Complete instrumentation engineering from measurement concept and device selection through loop verification and handover.
Instrumentation engineering
Instrumentation engineering converts process, safety and operating requirements into measurable variables, suitable field devices and clearly defined interfaces. The work is coordinated with process, piping, mechanical, electrical and control system disciplines so every signal has a documented purpose and installation basis. • Measurement and control philosophy • Instrument index and I/O list • Device selection and datasheets • Range, material and process connection definition • Vendor document review • Instrument location and accessibility review
Detailed design and documentation
Consistent engineering documents reduce interface errors during procurement, panel construction, installation and commissioning. Tag data, signal characteristics, power requirements, hazardous area information and termination details are maintained across the relevant project records. • Loop diagrams • Hookup and installation details • Junction box and cable schedules • Termination and marshalling information • Control valve and flow element calculations • Cause and effect and alarm data coordination
Control system integration
Field instrumentation must be integrated as complete measurement and control loops. Signal types, fail states, diagnostic behavior, scaling, alarm limits and device communication are aligned between the field design and DCS, PLC or safety system configuration. • Analog and digital signal definition • HART and fieldbus integration • Remote I/O allocation • Scaling, engineering units and alarm limits • Valve and motor interface coordination • Safety instrumented function interface support
Inspection and commissioning support
Support during fabrication and site execution helps confirm that specified instruments, panels and connections match the approved design. Testing progresses from document and hardware checks through calibration, loop verification, functional testing and final record completion. • Panel and package inspection • Instrument calibration review • Loop checking • Valve stroke and fail position testing • Functional test support • Punch item follow up and as built documentation
