[TowerTalk] Loos Tension Gauge

[Tom Rauch]

Comparing a link of approximately 1/4 inch OD Fiberglass
guyline (probably Phillystran) to 1/4 inch EHS steel, both
in series so they have exactly the same tension, I measure:

30 on gauge scale with EHS
20 on gauge scale with Fiberglass

33 EHS
23 Fiber

35 EHS
25 fiber

The scale on the PT-2 Loos gauge appears to move by
somewhere about the square root of the tension increase
(actually a bit more).

30 translates to about 680 pounds tension.
20 translates to about 300 pounds tension (if it
extrapolates that far)

Hardly the same, which makes sense looking at how the Loos
gauge works. It is indeed very material sensitive with
harder or stiffer material reading higher at the same
tension, which makes sense also when you think of how the
gauge works.
