ORDERING INFORMATION

When the desired output of a length sensor and wheel combination is either

in inches, feet, yards, or meters selection of the proper combination is relatively

straight forward. For example, with a 1-foot wheel circumference, a 1 PPR

Rotary Pulse Generator will deliver 1 pulse/ft, 12 PPR would deliver 12 pulses/

ft (1 pulse/inch); 100 PPR would yield 100 pulses/ft; and 120 PPR would permit

measuring to 1/10th of an inch (1/120th of a foot).
