1. 0 O VERVIEW

The CHECK•LINE®Type SY Cable Tensiometers are used to measure or compare
static tensions in long, moderately flexible galvanized or stainless steel wire ropes,
fiberglass rods and other cables with similar stiffness. The Model SY-600 covers
diameters from 3/16" to 1/2" (4 to 12mm) for tensions of 400-3000 lbs (200-1500 kg).
The Model SY-1000 covers diameters from 1/2” to 1” (13 to 24mm) for tensions of
850-5500 lbs (400-2500 kg). Select the model by cable diameter and range involved in
your application.

1.1 Operating Principle

SY Cable Tensiometers employ the three-roller system for operation, where the
outer two rollers act as reference points and the middle, sensing roller responds
to a fixed spring force behind it to cause a cable deflection which is inversely
proportional to the cable tension. The precision dial indicator on the opposite
side of the cable measures this deflection with a very high degree of accuracy.
This deflection can then be converted into pounds, kilograms or Newtons force
tension by referring to a chart or curve, which has been prepared in advance for
the cable material and size involved. (Refer to Procedure for Preparing SY
Tensiometer Calibration Charts, below). U-grooved rollers are used in lieu of
points or blocks to minimize friction and cable surface marring.

1.2 Tension Measurement

As noted above, tension measurement requires reference to a calibration chart
or curve for each cable type and size, prepared by the purchaser or a local lab
facility, at the purchaser’s expense. (ELECTROMATIC’s lab facility maximum
capacity is 3300 lbs). The attached sample copy of a chart and curve was
prepared for a customer's SY-600 Cable Tensiometer for 7X19 SS 5/16" cable.

1.3 Tension Comparison or Balance

This method permits operation without reference to a Calibration Chart.
However, it does require that at least one cable be under acceptable tension,
be less than the maximum tensions cited above, and that the other cables
involved are of the same type, size and stiffness. The deflection it causes can
be considered to be the “standard” deflection for the tension involved. The
deflection can then be compared to the deflections found in the other cables.
