Triaxial variable-capacitance accelerometer for flight test and other aerospace apps introduced by Endevco

Oct. 25, 2021
The 7298A offers performance over temperature and near-instant recovery after shock for flight testing and other high-accuracy motion measurement.

DEPEW, N.Y. – Endevco, an Amphenol company in Depew, N.Y., is introducing the model 7298A triaxial variable-capacitance accelerometer to provide high thermal stability and accuracy to measure low-frequency accelerations in aerospace and automotive applications.

Typical applications require the measurement of whole body motion in three mutually orthogonal directions immediately following shock motion or in the presence of severe vibrational inputs. Damping prevents resonating and flat frequency response down to DC ensures faithful low frequency accuracy and wide bandwidth.

The 7298A offers guaranteed performance over temperature and near-instantaneous recovery after shock for aircraft flight test and other high-accuracy triaxial motion measurement, including trajectory monitoring, modal analysis, flutter testing, vehicle dynamics testing, and flight testing of electric vertical take-off (eVTOL) aircraft.

The 7298A comes in 2-, 5-, 10-, 30-, 50-, 100-, and 200-G ranges. Each axis of the triaxial accelerometer uses a variable-capacitance MEMS sensing element. Gas damping and internal over-range stops help withstand high shock and acceleration loads.

The triaxial sensor is housed in a hermetic screw-mount package with integral hermetic receptacle. An eight-conductor model 3911 cable that accompanies the 7298A features PFA conductor insulation and jacket with a mating nine-socket plug on one end, and tinned pigtails on the other.
