Rotational Speed Sensor Type, Optical probe for measurements of rotational speed
FUA9192
Rotational Speed Sensor Type
● Optical probe for
measurements of rotational speed,
designed as retroreflective photoelectric sensor for
photoelectric detection of rotational speeds or events.
● For evaluation
of the pulses, the tachometer probe is
equipped with a specific frequency meter module that
calculates the number of revolutions per minute from the time period between
two pulses. A stable read-out is achieved by averaging over a minimum of
500 ms.
● Easy application:
A reflective adhesive tape is attached to the moving part and the probe
is aligned with it. For function control purposes a yellow signal lamp at
the rear side of the probe will be on when the reflective adhesive tape
is recognised.
● To increase
the operation reliability the sensitivity
can be adjusted through a potentiometer.
