At AITESA we apply a global vision of industrial control, combining process knowledge, multidisciplinary experience and advanced automation technologies. The result: stable, safe and scalable systems, designed to evolve along with operational and maintenance needs.
This discipline defines how process variables are measured, monitored and regulated, integrating field instrumentation with centralized control systems. It includes instrument selection and specification, control architecture design and integration with DCS and PLC or SCADA systems, ensuring accurate, continuous and reliable communication between all equipment.
We design solutions to monitor, regulate and optimize operations in real time, ensuring maximum efficiency, safety and reliability in all types of industrial facilities.
Control and Instrumentation engineering covers from the conceptual definition of the system to its complete integration in the plant. AITESA develops each project in an integral way, covering all the necessary stages to guarantee an efficient and safe automation, aligned with the client’s operational requirements. Its main activities include:
- Design and configuration of communications architecture, including DCS and PLC systems.
- Selection and specification of field instrumentation for variables such as pressure, temperature, flow, level and process analysis.
- Development of control loops and safety logic, adapted to the functional requirements of each process.
- Design of markings, instrumentation layouts and signal wiring, ensuring traceability and clarity in technical documentation.
- Configuration and parameterization of intelligent equipment, with advanced digital communication and diagnostic capabilities.
- Functional safety studies, including HAZOP, LOPA and SIL studies.
- Multidisciplinary coordination with process, electrical and mechanical areas, ensuring technical, operational and installation consistency.
