The engineers and designers of our Instrumentation division get involved in all stages of a project, from design to commissioning to:

• Design industrial operable facilities adapted to future user needs.
• Describe safety constraints including maintainability and operability: deviations review on PID (HAZOP), safety loops definition, security devices.
• Intervene during commissioning and startup phases.

ERAS provides to clients its competences in instrumentation:

• Instrumentation of process flow diagram in relation with technical teams
• Control loops design
• Data-sheet of measuring, detection and control equipment with recommendations of appropriate constraints solutions (products used , environment, accuracy required , ...)
• Control equipment sizing (control valve)
• FAT/SAT instrumentation equipments and installations
• Call to tender and construction management
• Instrumentation balance : Air consumption, amount of inputs / outputs for DCS, SNCC, SIS
• Installation drawings, assembly drawings
• Definition of safety loops (SIL calculations )
• Design and sizing for instrumentation cable trays

All studies for cable tray routing are directly performed on 3D model.

Our experienced teams provide their multi-industry expertise and the mastering of tools such as Aveva Instrumentation, Cims, Smartplant Instrumentation and GRIF. They are also certified QualiSil.

We also have expertise in industrial analysis & ATEX classification area:

Analysis system Design

• Needs and requirements definition for specific application analysis
• Selection of the analytical principle of on-line analyzer
• Selection of the analyzer from thoseavailable on the market
• Definition and design of the sampling system as a whole:

1. Sampling Point / return point.
2. Sample Pre-conditioning.
3. Sample Transportation.
4. sample Conditioning.
5. On-line Validation/calibration system for analyzer.
6. Sample collecting system (when process return is not possible).
7. Sampling (for laboratory analyzes).
8. Cleaning device.
9. Isolation device of analysis system.

• Definition of analysis system protection (box, shelter, HVAC, sensors, etc.)
• Definition and design of utilities.

ATEX zone classification

• Establishment of an Explosion Protection Document:

1. List of flammable substances
2. List of possible emission sources
3. List of electrical and non-electrical devices
4. Evaluation and definition of ATEX zones
5. ATEX zoning Plan

• Verification of devices conformity
• Definition of compensatory measures.
