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.
inputs like proximity switch, photo sensors, voltage pulses...
Multipliers and quartz crystal timebase.
± 1 R.P.M.
- No mechanical
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 R.P.M.!!!
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.
