Industrial Wide Belt Tension Tester
These testers are intended for INDUSTRIAL situations where:
- Belt tensions reach 6000 pounds...
- Belt widths reach 12 inches...
Need to measure tension in that big belt?
- It's EASY! -
The AWI and WB-170 product lines have you covered!
Guaranteed accurate readings.
Functions in the same manner as the basic AWI-I, except it services belts to 5" in width, and has a force range of 0-165 lbs (0-75 Kg.), and belt tension range of 0-2640 lbs (0-1200 Kg.).
Recommended for use on 3V-3VX belts of 8 strands or more; 5V-5VX belts through 6 strands; 8V belts through 4 strands; and is fully applicable for C-CX belts through 4 strands; and D belts through 3 strands.
SPECIAL NOTE: The AWI-V 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 five 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 five 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.
