Dynamic inclinometers
The dynamic inclinometers use an accelerometer cell and a gyroscope sensor for angle meas-
urement. The devices output angles according to the measurement axis or axes. The resolution
is 16 bit. A fusion algorithm calculates the inclination from the acceleration values and rotation
rate values. The fusion algorithm minimizes the effects of vibration and interfering acceleration.
The sensor can thus also output a stable signal in dynamic applications. The signal is processed
and linearized in order to output an angle.

Functions and operating modes
The inclinometers have two analog outputs, both of which are preset as current or voltage out-
puts. The analog signal output is proportional to the inclination angle. With the default setting,
the analog values of the sensors increase to indicate a clockwise rotation.
4.4.1
Setting options
The devices have an IO-Link interface and can be configured using the USB-2-IOL-0002 IO-Link
adapter via an FDT frame (e.g. PACTware).
The devices also have an Easy-Teach function. The Easy-Teach function (manual bridging) offers
the following settings:
n
Center point teach
n
Default setting
n
Teach-in of the start point of the measuring range (for 1-axis devices only)
n
Teach-in of the end point of the measuring range (for 1-axis devices only)
4.4.2
Output behavior
The two analog outputs of the sensor can be set as current or voltage outputs, regardless of
their default setting. The set output configuration applies to both analog outputs. The measur-
ing range can be configured as required. For 2-axis devices, the maximum values of ±85° apply.
Smaller angle ranges can be configured.
Current output
The device supplies each of the two analog outputs with an analog current signal. For 1-axis
devices, an inverted value of the inclination angle is also output via the second analog output.
For 2-axis devices, one axis is transmitted for each analog output.
The following output configurations can be set as current or voltage outputs, regardless of the
factory setting:
n
0…20 mA
n
4…20 mA (default setting, B…N…-QR20-2LI2…)
