TEI

What TEI does

TEI (Technologies et Équipements Industriels), founded in 1973 and headquartered in Paris with manufacturing in Ivry-la-Bataille, Normandy, designs and manufactures specialized test benches, calibration stands, and distributes pressure sensors for industrial measurement applications. The company is led by President David Cayez and operates as a privately held French SAS (T.E.I SAS). TEI operates at the intersection of mechanical, hydraulic, pneumatic, and electronic engineering, delivering turnkey solutions that include in-house design, assembly, worldwide delivery, installation, staff training, and on-site calibration and maintenance. Core products span aerospace test benches (production acceptance, component overhaul, development), generic test systems (pneumatic, electric, hydraulic, mechanical), calibration stands (pressure, flow, force, torque, displacement, electrical quantities), and sensors distributed from affiliated EFE (L'Essor Français Electronique), which contributes proprietary thin-layer (couche mince) sensor technology used in miniature, aerospace-qualified, and nuclear-rated pressure sensors.

The company's primary served market is aerospace OEMs and MROs, where TEI has been a supplier for 30 years and where it claims 20+ years of specialized experience in oxygen application test stands. Secondary verticals include transportation, defense, nuclear energy, research, and medical. Revenue is generated through quote-based hardware sales of test benches, calibration stands, and sensors, plus professional services for maintenance, calibration, and custom software development (primarily LabVIEW-based). Customer engagement is enterprise field sales supported by trade show participation (MRO Barcelona, MRO Middle East, Paris Air Show), a website with technical documentation, and direct contact (phone, email, online forms). Geographic reach is claimed to be global, with explicit installations in Singapore, the Middle East, and Europe, though the bulk of evidence points to a France-centric operational base of 27 employees.

Commercially, TEI runs a contact-based, project-driven sales model with no public pricing, multi-year service contracts (preventive maintenance, re-calibration), and tiered payment terms (orders under €500 due on receipt, €500–€5,000 at 30 days end-of-month, over €5,000 with 30% deposit). The product portfolio has been refreshed continuously since 2020 with new launches including the PHE791 ultra-miniature sensor, PGA257 aerospace-qualified sensor, BC300/BC310 torque calibration benches, PNA160 nuclear sensor, and B006 proof/burst/leak test bench, while capacity was expanded in 2020 with a new 150 m² air-conditioned workshop. The company shows no signs of external institutional investment, operating as an owner-managed SME.
