Risk of Personal Injury
When this instrument is being used in a critical process that could cause property damage and
personal injury, the user should provide a redundant device or system that will initiate a safe
process shutdown in the event that this instrument should fail.
5.1 Positioning
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 electromagnetic interference
in that location. If you plan to use air purging, you need to have an air connection available. Wiring and conduit
runs must be considered, including computer wiring and connections, if used.
5.2 Distance to Object
The camera provides different lens models to accommodate a wide range of applications. Each individual lens
provides different thermal images (Field of View) and minimum detectable pixel sizes (Instantaneous Field of View).
The optical diagram below shows the principal graphical representation for measuring distance over the field of
view. The manufacturer provides a tool for calculating image sizes, see section 9.1

5.3 Focusing
After the camera has been mounted, it is important to make sure that the optimum focus has been established for
the given mounting distance. It is important to focus the camera correctly to obtain the sharpest image of the target
you wish to view. The motorized focus of the ThermoView camera can be set via the PC software or the built-in
web server application.
If the installation distance changes later, it must be ensured that the focus distance is adjusted accordingly.
5.4 Mounting
The camera installation requires the most planning effort. The camera needs to be accurately mounted in
relationship to the target. Adjustments to align the camera with the target may have to be designed into the camera
