C. Examples of use
Differential thickness measurement with wide wooden boards
Two opposite facing sensors enable non-contact measurement and control of the thickness of the wood or wooden
boards. A change in thickness is indicated at the analogue output of the master. 12 mA corresponds with the taught
reference thickness of the object.
INFORMATION
Although a FT 80 RLA sensor only has a measuring range of 500 mm respectively, it is possible to
measure excess width using master-slave mode. The solution is in the alignment of both sensors
(illustr. 20). The necessary measuring range depends on the maximum difference in thickness.
Slave
The analogue output on the master sensor supplies
INFORMATION
To achieve optimum use of the measuring range, the object must be positioned in the centre of
the measuring range.
