Esterline Advanced Sensors includes five operating units and a global network of aftermarket service facilities. We are dedicated to serving the needs of our customers and to achieving market and technology leadership within our niche.
Product Brands

Our four product brands – Auxitrol, Norwich Aero, Weston and Esterline Mexico – reflect development and manufacture of sensors (mainly temperature, pressure, speed and mass flow sensors) that cover the spectrum of aero-engine, aero-equipment and airframe applications, as well as industrial and marine derivatives.


We offer customers a full Tier 1 capability operating as a prime supplier of the engine sensor suite, sourcing a broad range of sensors within our own operating divisions and the balance from industry-recognized sub-tier partners of equal standing and qualification. Individual products or sub-systems can also be supplied. Esterline Advanced Sensors offers outstanding research, design, development, testing, manufacturing and aftermarket services, joining together the forces of our world-class people and facilities, combining their strengths with sub-tiers and forging partnerships with customers to enable them to compete with maximum effectiveness.

We have agents representing Esterline Advanced Sensors in Europe, the Middle East, the Far East and South America, providing a global team committed to satisfying our customer’s needs.
