LWH transducers are designed for
the direct, absolute measurement
of displacement or length in
control regulation and measuring
applications. High resolution
(0.01 mm) combined with a stroke
length of up to 900 mm permits
the accurate measurement of
linear displacement. Rack and
pinions or similar devices are not
required because the design of
the transducers is such that they
may be built directly into the
mechanical system.
Tighter tolerances on the ex-
truded body combined with a
special surface treatment permit
high operating speeds and
reduced wear. A pivoting front
bearing over comes “stick-slip”
operation even where some
angular or out of parallel errors
are present. The technique for
fixing and making connections to
the resistance track ensures the
highest degree of reliability even
under harsh working conditions.
The transducer has mounting
grooves on all four housing
surfaces. Thus the transducer
can always be mounted with the
resistance element directed
upwards (recognizable by the
position of the middle mounting
groove directly across from the
resistance element), independent
of the mounting surface.
By mounting overhead on
difficult-to-reach machines it
is possible to premount the
clamps to the mounting surface
and then simply “snap-on” the
transducer.
