Error-Free Inclination Measurement for Dynamic Applications with the Inertial Measurement Unit F99

The inertial measurement unit IMU F99 combines inclination measurement, accelerometer, and gyroscope in one device. The intelligent sensor fusion algorithm of the inertial measurement unit is able to link the acceleration and rotation rate measurement data in such a way that the system can compensate for external accelerations without any loss of time. With the new version, this sensor fusion algorithm is now individually configurable for the first time and can therefore be precisely adapted to the motion pattern of the respective application. Users can select the type of acceleration compensation in the software and at the same time specify a suitable compensation range. These configuration options improve angular stability during external accelerations and ensure that the IMU F99 always delivers optimal measurement results—whether for short-term impact effects such as a pothole or for linear acceleration trips. Users also have the option of outputting both raw and compensated data, allowing them to use all acquired values according to their needs.

Like its predecessor, the new IMU F99 is quick and easy to install. The sophisticated mounting concept, consisting of a robust metal mounting bracket and the sensor module, provides optimum impact protection and also simplifies any device replacement. If a sensor needs to be replaced, the metal mounting bracket remains mounted, only the sensor module is replaced—no new adjustment or calibration is required.

With an IP68/69K​ degree of protection, the inertial measurement unit from Pepperl+Fuchs is particularly robust and can be used in a wide variety of applications. For example, the IMU F99 is ideal for inclination measurement on mobile machinery and, thanks to E1 approval, also in public road traffic.
