PERIOD TIMER
Type :
GFP40
THE PERIOD TIMER LFT60 IS APPLIED WHERE
IT IS NECESSARY TO CONTINOUSLY
CALCULATE AND VISUALIZE THE TIME IN
WHICH A DETERMINED OPERATION IS
EXECUTED ( NORMALLY A TRANSLATION ),
STARTING FROM A RELATIVE SPEED
MEASUREMENT AND READ THROUGH AN
IMPULSE SENSOR. ITS EASY USE AND
UTMOST FLEXIBILITY MAKE THIS INSTRUMENT
APPROPRIATE FOR MANY DIFFERENT
APPLICATION SUCH AS :
- TRANSLATION TIME ADJUSTMENT
- FIRING AND DRYING TIME ADJUSTMENT, ETC
- LIQUID FLOW TIME ADJUSTMENT ( COUPLED
WITH A CAPACITY TRANSDUCER ).

PRACTICAL EXAMPLES: ======
1) Display the rotational speed ( revolution per minute ) of a shaft counting pulses from a
proximity switch and using a 24 cog gear-wheel: - set the division factor = 24 - set the multiplier
factor = 60 (1 minute = 60 secs), in order to display the value with a minute time-base
2) Display the linear speed of a conveyor-belt in meters per hour, using a 500 pulses/rev
encoder, with 1 encoder revolution = 33.3 cm.: - set the division factor = 500 - set the multiplier
factor = 1200 ( 1 hour = 3600 secs; 33,3 cm = 1/3 m -> 3600/3 = 1200 ).
