The metal detector search head and control unit has been designed for use with
continuous motion conveyor systems, pipeline, pharmaceutical and freefall
metal detectors.
As standard, the control unit is secured at the end of the search head. This unit
enables suitably trained personnel to set up, change, calibrate, and obtain
results from the system through a menu-driven user interface. The control board
can be fitted with an optional board providing the following serial link options – 1
x RS232 (hardware hand shaking). 1 x 20ma current loop, and 1 x RS422 (both
software handshaking). See the
manual.
The control board can also be fitted with an optional external sensor board
enabling the following functions to be supported - Product registration photoeye.
Reject device actuation or confirmation of a rejected item entering a reject
collection container, photoeye or a movement sensor can achieve this. Reject
bin full sensing photoeye. Variable speed sensing using a shaft encoder.
