Mounting Instructions Data Loggers

Proper mounting of the data loggers is essential for the correct measurement of dynamic loads. Before starting data recording, verify that the data loggers have been mounted correctly. The MSR data loggers should be firmly attached as close as possible to the object to be monitored, preferably directly to the object itself. Mounting the data logger on the packaging or on the transport vehicle may lead to deviating measurement results. Secure the data loggers to the object using the designated mounting holes. Alternatively, the data loggers may be secured using strong magnets or high strength industrial adhesive tape.

Orientation

Align the axes of the data loggers with the main directions of movement. The data loggers can be mounted in any position. Make a note of the position and direction of the axes for later evaluation.

Determining the inclination

In the MSR 175, MSR 175Plus, and MSR 175Pro models, the accelerometer measures gravitational acceleration directed toward the center of the Earth (0 ≤ X, Y, Z ≤ ±1 g). The inclination angle of the data logger can therefore be determined approximately using trigonometric functions describing rotation about a single axis within a range of 0 to ±180°.

Example: ACC x = -0.518 g, ACC y=0.425 g, ACC z=0.741 g

Housing types: Outlines, mounting hole patterns, screw fixings

1) The GPS antenna of data logger MSR 175Plus, (housing type B56) should be attached to the outside of the packaging. The back of the antenna is magnetic. On a non-magnetic body it can be positioned and secured with a wrapping foil.
