Universal Sag Indicator- Measures Wire Sag Directly
The Evans Sagwatch, as described in the current edition of the
"Lineman's Handbook" has now been modified to extend its range,
while reading closer than 1% accuracy.
This high quality instrument, the UNISAGWATCH, specially
calibrated, is applicable to any wire size regardless of span,
tension, temperature, or composition, size or weight of conductor;
-- and is now ready for immediate delivery.
The UNISAGWATCH carries logarithmic scales calibrated in
feet and decimals for both 3rd and 5th returns of a mechanical
wave, providing direct reading of sags up to 100 feet. Sagging with
this instrument eliminates the need for conversion tables and
setting and sighting targets.
For special use, the UNISAGWATCH also contains an inner
scale to read time to the tenth of a second. By use of the table in
the instruction book accompanying each UNISAGWATCH, the
time for any number of returns may be converted to sag in feet.
The UNISAGWATCH has a 7 jewel Swiss movement, in a stainless steel case. It is water resistant, dust
protected, shock resistant, anti-magnetic, and self-compensating with an unbreakable mainspring.
The principle of sagging by wave-timing has long been recognized. The use of the UNISAG-WATCH
to determine sag simply, rapidly, and accurately can save many valuable manhours by eliminating the
setting and sighting of targets. The UNISAGWATCH is also particularly suitable for use in poor visibility,
due either to weather or, in these ecology-minded days, to a selectively cleared Right-of-Way. Checking
sag in a 'hot' wire by an observer on the ground may also be readily accomplished by use of the
