Vibration, Shock, and Acceleration

Flight Test Accelerometers – For Civilian and Military Applications

For 40 years, PCB

has assisted customers in the Aerospace and Defense industries, with the design and manufacturer of sensors for flighttesting and monitoring of fixed wing, rotary aircraft, missiles and launch vehicles. In addition, when testing and monitoring applicationsrequire specialized sensor packaging, testing, or performance, PCB

can provide sensors that are custom engineered to meet demandingor unusual tasks. The sensors below represent a small sample of such units. Quality Standards:

AS9100:2004 certified; ISO 9001:2000 certified; A2LA accredited toISO 17025; Manufacturing capabilities to certain MIL & aerospace standards; Some designs have been qualified to RTCA-160E.

Recent Programs:

Airbus A380; Boeing 787; Delta Launch; F-18 Flight Test; GEnx

™

Engine; Ground Missile Defense (GMD); National MissileDefense; Titan launch vehicle.
