The most important part in the installation process is preparation. Please read Section
2.1, Preparation, thoroughly before proceeding with the mechanical and electrical
installation sections.
2.1
PREPARATION
Sensor location and configuration depends on the application. Before deciding on a
location, you need to be aware of the ambient temperature of the location, the atmos-
pheric quality of the location, and the possible electromagnetic interference in that
location. You need to be aware of the spot size on your target and how far away the
sensor needs to be mounted. Also, if you plan to use air purging and/or air or water
cooling, you need to have air and water connections available. The following subsec-
tions cover topics to consider before you install the sensor.
2.1.1 Sensor Location
The desired spot size to be measured on the target will determine the maximum
working distance and appropriate focus model. The target spot size must contain the
entire field of view of the sensor (Figure 2-1). It must be the same as or smaller than
the desired spot size.
