Multi-Axial Accelerometers DESCRIPTION Series 3001 Multi-Axial accelerometers are hermetically sealed instruments for simultaneous measurement of acceleration on one, two, or three axes: vertical, longitudinal, and lateral. These accelerometers consist of up to three separate, rugged seismic sensors responding to forces along each axis. Each sensor consists of a bending beam, with strain-gages forming a full Wheatstone Bridge, and a mass. An advanced solid-state electronic signal conditioning package compliments the mechanical configuration. These units are designed for use in military and commercial aircraft which utilize digital flight data acquisition and recording systems. Each of the accelerometers meets the mandatory requirements of FAA and other worldwide regulatory agencies. They are designed to ARINC specifications 573 and 717, and tested to TSO C51a and RTCA DO-160. They are directly interchangeable with any accelerometer now in service and are compatible with any digital flight data recording system.
