EDDYSENSOR Operating Manual
FI1031BA Back Module
The back module of this unit
FI 1031BAfff
(where fff is the test frequency)
provides a coil connection and outputs for the analogue defect signal and
for the digital defect level. This unit is supplied in a number of frequency
versions:
5 - 10 - 20 - 50 - 100 - 250 kHz.
Output for the defect signal
to a recorder, bar graph or
oscilloscope
Output for the digital
defect signal, input for
end signal supression
in offline applications
I/O socket for the coil
Connection of display device
To connect peripheral devices such as a recorder, bar graph or oscilloscope
on which the signal is graphically displayed, use the socket Analog Signal
0 - 10V (R
O
= 100
Ohm).
