HDW Series Revolution Counter

Product Description

Model HDW Series are high speed, end
drive revolution counters that have the
rugged features of all Durant “H”
counters, with the addition of double
worm drive that produces speeds up to
2000 cpm. Lightweight precision
molded wheels reduce centrifugal force
and eliminate slipping. They are
particularly recommended for quick
starting and stopping machines, such as
coil winders and wire measuring or
reeling equipment and on applications
where continuous high speed
measuring is required.
