6.1 Select installation location
Observe the following instructions for the selection of the installation location:
►
The object
③
must be completely in the field of view
④
.
> The size of the field of view depends on the sensor type and is indicated in the data sheet. The size of
the field of view also depends on the distance of the sensor to the object
⑤
: With increasing distance
the field of view becomes larger.
►
Take tolerances into account when positioning the object.
►
When determining the distance between sensor and object
⑤
take the measuring range of the sensor into
account.
> The measuring range is indicated in the data sheet of the sensor.
►
Select a distance as small as possible between sensor and object
⑤
.
> If the distance is as small as possible, the object is detected with the maximum resolution.
►
Avoid any strong ambient light and sunlight at the installation location.
> An extraneous light level of over 8 klx (with solar spectrum) causes measurement errors. In fact, only
the infrared component between 800 and 900 nm is of concern.
►
Avoid installation in heavily polluted environments.
> In heavily polluted environments the sensor lens will get dirty despite downwards orientation
①
.
►
Avoid transparent panes between the sensor
①
and the object
③
.
> Transparent panes reflect part of the light even if a very clean glass pane is used.
If the instructions are not observed, measurement errors may occur.
