EFE Information

Designer and Manufacturer of Premium Pressure Sensors since 1973 L’Essor Français Electronique (EFE) has been developing and manufacturing a complete range of pressure transducers since 1973. During this time, we have designed our proprietary advanced sensing technologies and created a unique range of high performance and miniature pressure transducers. To meet our customers’ high requirements, EFE decided very early on to develop its proprietary sensing technology for pressure transducers. Our thin film is manufactured using a physical vapour deposit, and more precisely sputtering process on a metal diaphragm (stainless steel, titanium, inconel, etc.). Thin film as used by EFE is the only technology which does not require any intermediary between the sensing element and the fluid to be measured as with an oil separator for silicon based sensors or O-rings for ceramic technology. These intermediaries are a weak point regarding the reliability and performances requested in customer’s applications. With our technology, the diaphragm is welded on to the pressure port and our wetted parts are fully metallic (stainless steel, titanium, inconel, etc.). Our company devotes considerable resources to research and development programs, co-operating with several research institutes, universities and schools of engineering. Our products are designed to be used reliably in the most difficult and demanding environments. From the beginning, we have catered for customers in the aerospace, marine, defence, automotive, motorsport, nuclear, oil & gas, research sectors and numerous industrial applications. We work on national and international civil and military programs. Our 47 years of existence have enabled us to develop a very diversified clientele of major accounts. A significant part of our group’s activity is carried out on the export market. Sensors from EFE are sold in France and overseas: in Europe, America and Asia.
