Transducers employing the
NOVOSTRICTIVE® touchless
magnetostrictive measuring
process for direct, precise and
absolute measurement of linear
position in control, positioning
and measuring applications.
The measurement is accomplished
using a passive position
marker which is available
in a guided or in an unguided
version.
Side coupling of the position
marker reduces the installation
assembly dimension, prevents
the pump effect of slide
arms and permits stroke
lengths up to 4500 mm.
The unguided version makes
installation even simpler, and
the wear-free operation enables
unlimited mechanical life
expectancy and unlimited traverse
speed of the position
marker.
The temperature coefficient of
the transducer is extremely
low thanks to the measuring
principle, design and selected
materials.
The high mechanical ruggedness
of the transducer combined
with the underlying measuring
technique stands for
the systems high resistance
against shock and vibration.
The active sensing element is
encased in an aluminum housing
rated to IP 67. This makes
the transducer resistant to
contamination, dust, moisture
and oils.
Mounting is accomplished
using clamps that allow precise
mechanical adjustment.
A sophisticated ASIC in the
transducer provides for standard
absolute output signals.
The transducers series TLM
with quadrature output are directly
compatible with common
encoder input devices.
So the TLM with all it’s advantages
like robustness, dust insensitiveness,
mounting
friendlyness and it’s attractive
price now is applicable for
present glass or magnetic
scale applications in linear positioning
devices.
Output are compatible A/ Zsignals.
A and B do have
phase difference of 90° to
each other. The output is optionally
available as RS422
as puhs-pull output (level
or 24 V). Exceeding the maximum
velocity does not result
in losing increments after lowering
the velocity below
specified maximum.
To make a reference drive obsolete,
the
sensor puts out
the actual position value during
the initialisation phase
the processing unit (power-
burst).
