Chapter 2: Installing the LDT
Mounting
The transducer can be mounted vertically or horizontally
using the supplied SD0522000 mounting brackets. The
mounting brackets slide in the grooves on the lower part
of the extrusion and clamp down when tightened. It is rec-
ommended to use one mounting bracket on each end and
every three feet between.
Ferro-magnetic material, which is material readily magne-
tized, should be placed no closer than .25” from the sens-
ing surface of the LDT.
Magnet Assembly
Magnet choices are the Floating Magnet or the Slide Mag-
net assemblies. When using the Floating Magnet assem-
bly SD0551500, the magnet should be installed within ¼”
of the sensing surface. The magnet assembly should also
be installed in such a manner that it remains an even dis-
tance from the aluminum extrusion throughout the entire
stroke. Improperly installed magnets can result in output
signal non-linearity, or loss of Magnet signal.
Units can be ordered in span lengths up to 180 inches
long in .1 inch increments. The optional slide magnet is de-
signed to move effortlessly along the transducer in guide
tracks, or the standard floating magnet assembly can be
positioned up to 1/4” above the unit. A variety of hardware
is available for attaching the magnet slide to the moving
portion of the process.
The 957 Brik™ has a few truly unique features. One fea-
ture is the LDT’s auto-tuning capability, the ability to sense
a magnet other than the standard slide magnet and adjust
its signal strength accordingly.
