4HE 4!#(42/,¸ TACHOMETER IS AN APPLICATIONS ORIENTED SINGLE OR DUAL CHANNEL COMPUTING TACH

OMETER WHICH USES THE PERIOD MODE OF FREQUENCY MEASUREMENT TIME PER EVENT

5SED AS A SINGLE CHANNEL TACHOMETER THE 4!#(42/,¸ TACHOMETER MEASURES THE RATE OF INDUSTRIAL EVENTS SUCH AS THE RATE AT WHICH LIQUID IS PASSING THROUGH A PUMP OR THE RATE AT WHICH BOTTLES ARE

PASSING ALONG A CONVEYOR BELT 4HE TACHOMETER DISPLAYS THESE RATES IN ENGINEERING UNITS SUCH AS &03

FEET PER SECOND '0( GALLONS PER HOUR 20- REVOLUTIONS PER MINUTE AND OTHER RATES

5SED AS A DUAL CHANNEL TACHOMETER THE 4!#(42/,¸ TACHOMETER CAN READ TWO UNRELATED SPEEDS

OR CAN COMPUTE SIX MATHEMATICAL FUNCTIONS FROM THE INPUT SIGNAL FREQUENCIES OF TWO RELATED SPEEDS

)N ADDITION THE 4!#(42/,¸ TACHOMETER MAY BE USED AS A BI DIRECTIONAL TACHOMETER TO MEASURE
