Instrumentation Engineering
Field instrumentation engineering that connects process requirements to reliable measurement, control, shutdown, and operating decisions.
Instrumentation
Accurate measurement starts with sound engineering.
Instrumentation is where the control system meets the process. QIA-SIX Engineering supports the selection, specification, installation, documentation, and commissioning of process instrumentation and final control elements.
We focus on applications that are technically appropriate, maintainable in the field, compatible with the surrounding system, and clearly documented for construction and long-term operation.

Integrated Engineering
Controls and instrumentation should be engineered together.
Instrument choices affect control performance, diagnostics, alarm behavior, maintenance burden, and system architecture. By coordinating controls and instrumentation engineering, QIA-SIX can reduce interface gaps and help ensure the field design and control-system implementation support the same operating objective.
Typical integration points: I/O type and range, scaling, fail state, alarming, valve action, interlock requirements, networked instruments, package-unit interfaces, diagnostics, and commissioning test criteria.
