In electrical diagnostic instrumentation, two installations measuring the same quantity rarely need the same instrument. Working pressure, gas temperature, distance to the sampling point, the protocol used by the control system or the space available in the room completely change what the right configuration is.
That is why Amperis does not sell you a catalogue reference: we define with you the instrument that solves your measurement. That preliminary work — understanding the application, adjusting the configuration and equipping it with the right accessories — is part of every supply, not a separate service.
The application first, the instrument second
Before proposing a model, our engineers need to understand what is going to be measured and under what real conditions. These are the questions that stop an instrument that looks correct on paper from turning out to be useless in the field:
- What is measured, and how demanding is it. Expected range, accuracy required, whether you need the absolute value or the trend, and how often it has to be measured.
- Under what conditions. Process temperature and pressure, presence of moisture or particulates, corrosive atmosphere, vibration or outdoor exposure.
- Where it is installed. Control room, outdoors, an existing cabinet with tight space, or a portable measurement that travels between substations.
- Who is going to use it. A laboratory, a maintenance team on the road, or an unattended system that should only raise an alert when something drifts out of limits.
- What it integrates with. Your protocol and control system, the logging format required, the traceability needed for audit or regulatory purposes.
That conversation produces a reasoned recommendation. If a simpler instrument covers the need, we will say so; if the application demands performance the intended model cannot deliver, we will say that too.
Precise configuration
Our instruments are configured, not picked from a closed list. On the same analyser or the same camera, the following are defined, among other parameters:
- Mounting format. 19" panel mounting, weatherproof wall enclosure with IP65 protection rating, or a portable version, depending on where the instrument is going to live.
- Sensor range and type. Selection of the sensor suited to the real working range, including measurements under extreme temperature or pressure conditions.
- Remote sensor placement. The sensing element can be separated from the analyser — up to 25 metres with extension cables on certain models — when the measuring point is inaccessible or sits in a hostile area.
- Outputs and communications. 0-5 V analogue outputs and 4-20 mA current loop, RS232 or RS485 communications, Modbus RTU protocol or Ethernet, so the instrument speaks your control system’s language.
- Alarms and automation. Programmable relay circuits with the thresholds set by your maintenance procedure.
- Calibration. Definition of the user-selectable gas compositions and of the periodic verification procedure.
Each of these decisions is made with a specific reason from your installation behind it. That is the difference between an instrument that gets used and an instrument that ends up in a cupboard.
Accessories are not an add-on
What makes a measurement possible is often not the instrument itself but what comes with it. Getting this part wrong is the most common reason for a commissioning to be delayed, or for the data not to be reliable.
We define and supply the complete set: calibration kits, additional probes and sensors, sampling systems — including multiplexed systems when several points have to be monitored with a single analyser — extension cables, specific filters and manifolds, mounting cabinets and brackets, auxiliary pressure or vacuum sensors with their standard fittings, and the communications and data logging software.
The aim is for the instrument to arrive ready to install and measure, without discovering in the field that a part is missing.
What you get from this advice
- A reasoned technical recommendation, covering the alternatives available and why we propose one of them.
- The detailed configuration of the instrument, parameter by parameter, matched to your application.
- The complete list of accessories required, separating the essential from the advisable.
- A quotation that corresponds exactly to that configuration, with no generic line items.
- Direct contact with engineers who know the instrument, after the sale as well.
Why our judgement
We work exclusively on state-of-the-art instrumentation for the diagnosis and testing of electrical substations. That specialisation is what allows us to recognise an application quickly and anticipate its problems.
Our instruments have been sold in 63 countries, across very different installations and climates. The company is certified to ISO 9001:2015, audited by SGS, and added the ISO 14001 and ISO 45001 certifications in 2024. Supplier qualification multinational Achilles has qualified us for supply to electricity utilities in Spain, Portugal and Italy.
