6060 Is an accurate digital speed (R.P.M.) indicator
for measuring R.P.M., rates per minute.... etc It
is widely used in centrifuges, stirrers, pharmaceutical
and laboratory equipments, digital read outs, control
panels, drives, textiles,
chemicals plants.... etc
Wide range from 10 to 9,999 R.P.M.
Accepts inputs like proximity switch, photo
sensors, voltage pulses...
P.L.L. Multipliers and quartz crystal timebase.
Accuracy ± 1 R.P.M.
No mechanical moving parts.
An output coming from a transducer is filtered,
signal conditioned and chopped. Finally it is converted
into square waves. The square wave is passed through
RLL multipliers. This output is gated by a precise
time base generated through piezo crystals and then
counted. This counts are displayed on bright LED's
.... It's nothing but R.P.M. with accuracy of±1
A) RLL circuitry requires minimum 2.5 pulses per
second i.e. 2.5 x 60 = 150 R.P.M. It's lower limit.
If more than one pulse is given in one rotation
then lower limit is reduced, eg if 2 pulses in one
rotation than 75 R.P.M. i.e. If n pulses per rotation
can give measurement of 150 * R.P.M.
B) 60 tooth gear wheel can give R.P.M. upto 10.
Proximity switch, photo sensors,
voltage pulses, 60 tooth gear wheel etc.
to 9,999 R.P.M. in normal case.
B) Lower limit can be reduced by factor n if n pulses
in one rotation.
C) With 60 tooth gear wheel 10 R.P.M.
every second i.e. 1 second.
