Accelerometers Accelerometers Accelerometers

BEI Precision manufactures flight worthy pivot and jewel accelerometers and displacement sensors for flight control systems and fatigue vibration monitoring. Qualified and field proven, our accelerometers operate over a wide temperature range, are very accurate, and have a long operating life requiring no scheduled maintenance.

Linear Accelerometers

Linear Servo Accel-erometer Model 4311A

The Model 4311A is a miniaturized and rugged version of the obsolete Model 4310 accelerometer. This low-cost, high volume device is highly reliable and ideal for missile control and aircraft autopilot applications. The low operating voltage produces a high-level, high accuracy signal output without amplification.


Linear Servo Accel-erometer Model 4384A

The Model 4384A is a proven performer in applications of flight control, autopilot, guidance, and instrumentation for missiles, spacecraft, and aircraft system. This device transmits accurate, high sensitivity outputs to low-level acceleration measurements under harsh environmental vibration and shock.


Inertial Angular Displacement Sensor

IADS Model 8301F

The Model 8301F is a very precise fluid rotor displacement sensor that detects angular motion from 2 to 2000 Hertz. Ruggedized and qualified for space flight, the 8301F can achieve sensitivities of 100,000 Volts/radian with noise floors of 50 nanoradians RMS or less. The detection threshold of this device has been shown to be well below 1 nanoradian.
