9 Angle definition (0x2044)

To be able to adapt the inclination sensor to the different applications as easily

as possible, the measured inclination information is converted into different angle

indications� The requested angle indication is set by selecting the respective

option�

With this angle definition a sensor coordinate system is used which is defined as

follows:

– The mounting plane corresponds to the XY plane�

– The z axis is perpendicular to the mounting plane (according to the right-

hand rule)�

– The X axis is represented by an edge of the mounting plate which shows in

direction of the printed X arrow�

– The Y axis is then perpendicular to the plane spanned by the Z and X axes�

9.1 Perpendicular angle (0x2044 = 0)

Using the indication of the two perpendicular angles the inclination of the sensor

coordinate system towards the direction of gravitation is described�

The first provided value corresponds to a rotation about the Y axis of the sensor

and is called "longitudinal inclination value"�

The value corresponds to the angle [°] which the gravitation vector spans with the

YZ plane�

The first provided value corresponds to a rotation about the X axis of the sensor

and is called "lateral inclination value"� The value corresponds to the angle [°]

between the gravitation vector and the XZ plane of the sensor�

In the case of an inclination in a plane (rotation of an axis with the second axis remaining

perpendicular) the perpendicular angle and gimbal angle are always identical�
