This *heavy-duty“ version
of the 360° potentiometer
AW 360 ZE is particularly
suited for applications where
rough conditions prevail.
Its robust design is especially
suited to for industrial plants
and heavy engineering industry.
The case is waterproof,
and the shaft passage is sealed
by a gland. Electrical connection
is effected on the side
by means of a plug. Apart
from direct analogue use, it
can be used in conjunction
with an external A/D converter.
In this case, the unit operates
as an angle transducer
with 12 bit resolution and
offering 10 bit absolute accuracy.
Contrary to the limitations
encountered with other potentiometers,
which have a dead
band of some degrees which
cannot be used, due to its
two wipers and its hybrid circuit
the AWS 360 ZE can be
used over all 360° of rotation.
The reset voltage at the beginning
and end of the saw
tooth are well defined, and
there is no function angle tolerance
as is normally associated
with potentiometers.
These features together with
output voltage is determined
by the applied voltage means
that units may be inter-changed
or replaced without the
need to adjust or trim. When
turning the axle in cw (view on
shaft end) the signal increases.
Other output signals on
request.
The transducer delivers a logical
signal quite separately
from the analogue output
which can be used to inhibit
the A/D conversion during the
reset period, in order to avoid
measuring errors.
