T.E.I

Specialist in sensors, instrumentation,
test benches and calibration stands for 47 years

T.E.I is part with L’Essor Français Electronique (EFE) of a group dedicated to high performance measurements since 1973.
We develop and manufacture standard and customised sensors and test benches.

The sensors

We offer one of the most comprehensive ranges of miniature and high performance pressure sensors on the market. It includes high performance sensors for test bench measurements and miniature transducers designed for on-board measurements in harsh environments.

If your application requires a customised product, we can adapt a standard sensor or develop a specific model based on your specifications. Our design office will study with you the most suitable solution within a timeframe compatible with your project.

For more information on our pressure sensors, you can visit the website of our sister company.

The test benches

T.EI. has a wide range of pneumatic, electric, hydraulic and mechanical benches. They are used in various industrial fields, for the development of new products, production and after-sales service.

A team of engineers is at your disposal to analyse or define with you the specifications of your test equipment. We provide a turnkey service including installation, staff training, remote technical support, maintenance and calibration of our benches, anywhere in the world.

The technology

To meet our customers’ requirements, EFE has been developing its own thin-film technology for pressure sensors since the early 1980s. This technology uses the principle of physical deposition (PVD) on metal diaphragms (stainless steel, titanium, inconel, etc.).

The thin film used to manufacture our sensors is the only technology that is fully metallic and guarantees the performance and environmental resistance required by our customers’ applications. Our technology does not require any “oil separator” or internal seal between the sensing element and the fluid to be measured. They are weak points for the technologies requiring such intermediaries and may prohibit their use in processes demanding high reliability: risk of pollution of the process by the oil separator, instability and inaccuracy introduced by the separator in the case of quick thermal variations of the fluid, incompatibility of the internal seal with corrosive fluids, etc.

With our technology, the diaphragm is welded directly to the pressure connection. The all-metal sensor is thus compatible with most media, even corrosive ones.

The design of the numerous test benches we have built over the last 30 years has enabled us to develop a recognised know-how in our business area. In order to meet our customers’ specifications, we can rely on proven and innovative technologies, such as : accurate and dynamic pressure regulation, high quality technique for simulation of altitude, “plug & play” sensors management, own solution for PLC dedicated to high-performance measurement, to name a few.

Our fields of intervention

Our products are designed to be used reliably in the harshest and most demanding environments. We are involved in both civil and military and national and international programs.

Over 47 years of existence we have developed a very diversified customer base of key accounts, including manufacturers in the aeronautics (aircraft manufacturers, maintenance companies, equipment suppliers), automotive (manufacturers and Tier one suppliers), defence, space, energy (nuclear in particular) and research sectors.

A significant part of our group’s activity is carried out on the export market : in Europe, Asia, North America, the Middle East and North Africa.

Our know-how

Our design office has all the skills in-house to support you in your most ambitious projects: mechanics, instrumentation, simulation, CAD, metrology, electronics, pneumatics, hydraulics, automation and IT.

Our team of trained technicians, pipe fitters, metrologists and instrumentation specialists provide high-quality fabrication, on-site installation and maintenance.

Each product delivered passes a long cycle of testing and inspection to ensure that it is fit for purpose.

Our means

Located in Ivry la Bataille, 60kms west of Paris, close to major industrial and technological centres, our factory extends over more than 1500m2 dedicated to the design, manufacture and research and development of our products.

On this site, we have high-tech equipments for in-house production : electron beam and laser welding machines, leak detector, calibration stands for pressure, load, torque, displacement, temperature and electrical quantities, laser engraving, micro-wiring equipment (ball bonding), thermal test and burn-in chambers, endurance test bench, control and testing equipments, etc.

Our workshop dedicated to the assembly and testing of our test rigs has just been enlarged by more than 150m2, fully air-conditioned, to increase our manufacturing capabilities and to welcome our customers for final inspections in the best conditions.

These production facilities allow T.E.I. a complete control of the design, production, after-sales service and delivery times, in order to ensure our customers’ satisfaction. Equipped with a research and development laboratory, our design team is able to constantly develop our products and know-how.
