Industrial Wide Belt Tension Tester
Functions in the same manner as the basic AWI-I, except it services belts to 5" in width, and has a force range of 0-99 lbs (0-45 Kg.), and belt tension range of 0-1584 lbs (0-720 Kg.).
Recommended for use on 3V-3VX belts through 10 strands; 5V-5VX belts through 6 strands; 8V's through 4 strands; and is fully applicable for A-AX & B-BX belts through 6 strands; C-CX belts through 4 strands; and D belts through 3 strands.
SPECIAL NOTE: The AWI-III can also service multiple single stranded belt drives as well as banded belts. 
 
Operation: is the same as the AWI-I, except for step 4. Because force applied at the tubular handle is distributed equally across three spring-tension units, the pounds-force reading of each o-ring must be added together (i.e., add together the o-ring readings on all three plunger rods). Then, to calculate belt tension, multiply by 16.
Measure the length of span between sheave tangent points.
Set the bottom of the large o-ring at the correct point (on "50" if it is a 50 inch span) and set the top (small o-ring) down against the instrument's flange.
Depress the instrument downward at the center of the span until the large o-ring at the base of the instrument is in line with the tangent point of the drive. (This may be accomplished with a straight-edge, or a neighboring belt in a multiple belt drive.)
Read the number of pounds of force indicated by the small o-ring on the plunger rod, then multiply by 16 to determine belt tension
NOTE: Many belt manufacturers will specify the recommended plunger reading (in lbs. or kg.) for a specific application. In such cases, always follow the belt manufacturer's recommendation.
