This application shows how to measure and
calculate length of rolled film by the number of
generated pulse and roll diameter from a rotary encoder.
The rotary encoder is connected to a rolling shaft on a
film production line.
The RV-3150 Reversible Counter can compensate
the number of generated pulse so that an appropriate unit
can be set up on a display.
Connecting it to the PLC by using
comparator output enables output of command signal to
cut a film or to send an alert to a signal tower.
Continuous recording can be performed via
analog output signal to see fluctuation of rolling up
Connecting the RV-3150 to a PC via RS-232C
interface enables storing the measured data and so on.
