Type 4913 Is a combined
Stroboscope/-
Tachometer
for
visual Investigation and
accurate measurement
of
rapid, repetitive
motion, mechanical resonances, vibration
etc. It Includes a hand-held Lamp Unit
US
0008 and may be triggered from an Int.
generator,
power
llne
or
ext. tachometer sig-
nal
to
provide
a stationary
or
slow moving
Image
of
objects with motion frequency from
5 Hz
to
1 O kHz (0,3
to
600 k r /min). ·
separate
modes with adjustable time and phase delay
permit
observation at any required
point
in
the
motion
cycle. In addition a built-In
4-dlglt
display facllltates
direct
reading
of
motion
frequency
or
speed,
time
or
phase delay.
As
extra
Type 4913 can be coupled with the
Fibre-Optic Source Type 4915. This has a
reslllent 1,8 m long
fibre-optic
cable AE 6000
and outputs a convenient point source
of
lllumlnatlon
that
Is Ideal
for
stroboscopic
examination
of
small components, Intricate
mechanisms and microscope specimens.
For Internal Inspection
of
engines and other
machinery, an Endoscope Probe can be
connected.
