Inertial Measurement Unit IMUF99*B20

Product Description

Selectable output values and filters

Several selectable output values such as acceleration, rotational speed, inclination (Euler 

angle, Euler value, quaternions) and programmable filters allow you to perfectly adapt the mea

-

suring system to your application.
Parameterization and data transfer take place via the integrated CAN SAE J1939 interface.
In the following figure the signal path of input and output values is illustrated.
