Technical services for process instrumentation

Choosing the right instrument, putting it into service correctly, keeping it working and having someone to call when it does not — four things that decide whether a measurement point is worth having. SEMAC has done all four since 1994, on the instruments we supply and on the ones already in your plant.

Before the purchase order

Instrument Selection & Application Engineering

Choosing the measuring principle, the size and the materials for the actual fluid, line and duty — so the measurement is right before anything is installed.

Learn more From installed to actually working

Instrument Installation & Commissioning

Installation, configuration, loop checks, FAT and SAT, and operator training — everything between a delivered instrument and a measurement the control room can rely on.

Learn more Fault-finding first, then the fix

Instrument Maintenance & Repair

Fault diagnosis on site, repair in our own workshop with stocked spare parts, and a route to the manufacturer for what cannot be repaired here.

Learn more Someone who knows the device, on the phone

Technical Support for Installed Instrumentation

Remote and on-site technical support for instruments already in service — configuration, diagnostics, parameter changes and manufacturer software.

Not sure which of these you need? Describe the measurement point and what is happening at it, and we will tell you whether it is a selection problem, an installation problem or a device problem — those three have very different answers.

One instrument, four moments

These services are not a menu of unrelated offers. They are the four moments in the life of a measurement point where an engineer makes a difference.

  1. Before it is bought

    The wrong technology for the fluid, the line size or the flow profile cannot be fixed later by anything — not by configuration, not by service, not by a certificate. Selection is where most measurement problems are created.

  2. When it goes into service

    An instrument that is installed and wired is not yet a working measurement. Configuration, loop checks and a documented handover are what turn one into the other.

  3. When it stops behaving

    Fault-finding first, because a reading that has gone strange is as often an installation or process change as a broken device. Then repair — in our workshop where we can, at the manufacturer where we cannot.

  4. Every day in between

    Configuration questions, parameter changes, diagnostics read remotely, manufacturer software and firmware. Most of it is resolved without anyone travelling.

Two hubs, Thessaloniki and Athens, Monday to Friday 09:00 – 17:00, with extended hours and overtime when a plant is in an emergency.

Looking for a calibration certificate?

Traceable verification and calibration of flow, temperature and pressure instrumentation — with as-found and as-left values, stated measurement uncertainty and a report built to survive an audit — is the main work of this company and has its own section.
