PERIOD TIMER
Type :
LFT60
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 ).
