 Measure XYZ Acceleration and Roll, Pitch and Yaw

The new series 7556A sensors from Dytran Instruments, Inc. is a fully analog six degree of freedom (6DOF) sensor containing a MEMS based triaxial accelerometer as well as three MEMS based gyros. The sensor will provide the end user X,Y,Z acceleration (g’s) as well rotational information (roll, pitch, yaw expressed in degrees/sec) around those three orthogonal axis. 

A unique feature of the 7556A series is that it has been designed to have zero volts output for zero Engineering Units nominal input, thereby eliminating DC offsets typically found in many sensors of this type.

The sensor is powered with a wide voltage range of 5 to 30 VDC with typical current draw of 12 mA. The 7556A1 has a basic sensitivity of 400mV/g for the acceleration output and 1mV/degree/second for the gyro outputs. The 7556A2 has a basic sensitivity of 200mV/g for the acceleration output and 1mV/degree/second for the gyro outputs.

The sensor comes in a compact, lightweight, rugged, titanium, hermetically sealed package for harsh environment survival. The sensor also features a removable cable for convenience during installation and removal from the test article.

Typical uses for the 7556A series include but are not limited to the following test applications: vehicle dynamics, ride and handling, rollover, automotive safety, aerospace testing, large machinery including industrial off road, aircraft flight dynamics, aircraft ground test, helicopter evaluation, amusement ride, playground surface investigation. Note: This device is not ITAR controlled and is not suitable for use as an IMU due to performance specifications.
