5.1Positioning
Sensor location depends on the application. Before deciding on a
location, you need to be aware of the ambient temperature of the
location, the atmospheric quality of the location, and the possible
electromagneticinterferenceinthatlocation,accordingtothesections
describedabove.Ifyouplantouseairpurging,you
needtohavean
air connection available. Wiring and conduit runs must be
considered,includingcomputerwiringandconnections,ifused.
5.1.1DistancetoObject
The desired spot size on the target will determine the maximum
measurement distance. To avoid erroneous readings the target spot
size must completely fill the
entire field of view of the sensor.
Consequently, the sensor must be positioned so the field of view is
the same as or smaller than the desired target size. For a list
indicatingthe available optics, see section
3.2 Optical Specificati o ns
onpage6.
Theactualspot sizeforanydistancecanbecalculatedbyusingthe
following formula. Divide the distance D by your model’s D:S
number. For example, for a unit with D:S = 10:1, if the sensor is
400mm(15.7in.)fromthetarget,divide400by10
(15.7by10),which
givesyouatargetspotsizeofapproximately40mm(1.57in.).
