Development of data acquisition systems and instrumented equipments
In a general way, this field of activity includes any systems intended to convert electrical signals resulting from physical measurements into usable data. This consists of equipments and electronic subsets connected to sensors, as :
- Full standalone equipments, and connected equipments able to transmit digital data to a computer system
- Intrumentation networks for data monitoring
- Equipments operating in real time, or with storage capabilities for postponed processing with data delivered by memory sticks or by delayed wireless transmissions
- Full standalone instrumented systems, and also systems fully controled by a computer
TECHNETEA especially worked on the development (hardware & software) of electronic equipments for oilfield service companies, designing innovative solutions in particular in ATEX for the Mud Logging and the monitoring of physical parameters.
The competences are based on nearly 30 years of experience with oilfield services, and are at the root of the developments of electronic field equipments, laboratories equipments, instrumentations for geological and physicochemical analysis systems (PVT, calcimetry, gas chromatography), sensor fields data monitoring.
TECHNETEA also works on the development of high temperature electronic equipments (till 150°C at present) for very specific applications (eg : downhole tools).
Development of electronic equipments intended to be used in potentially EXplosive ATmospheres - ATEX
Related to oil, gas, mines or chemical industries, this type of equipments requires a particular approach from the very beginning of the design about the choices of the electronic structures and the mechanical protections, then also during the CAD of the printed circuit boards.
The ATEX approach can completely modify the preliminary definition of a project ; consequently it is strongly recommended to integrate all the ATEX aspects as soon as the definition stage of the equipment (or system) is initiated.
As a design office, TECHNETEA can ensure the complete design of an equipment, or only works on the ATEX aspects of the project as a consultant. Electronics being the main skill of TECHNETEA, the type of protection by intrinsic safety is preferentially used, but the other types of protection defined by the ATEX standards are sometimes also used in combination.
Because being in contact with a certifying labratory is something essential during the design stage, TECHNETEA usually works with INERIS, which is one of the two notified laboratories in France.
An equipment which is not designed from the beginning for a use in potentially explosive atmospheres, has thereafter very little chance to be able to be adapted for a use in this context.
