LD200 Series

The LD200 Series AC-powered LVDT
displacement transducers are ruggedly
constructed, delivering high performance at
a low cost. Along with a broad measurement
range, from 1.25 to 10 mm (0.05 to 0.40"),
these transducers have high resolution and
repeatability.
The coils are wound on a rugged bobbin
housed in a stainless steel case. Epoxybonded construction makes these devices
suitable for applications involving wet or oily
environments, or high levels of mechanical
stress (vibration, shock, etc.). The armature
assembly ensures friction-free movement
within the sensor because of the large radial
clearance of the bore.
These transducers offer excellent linearity,
low levels of residual voltage, and good
temperature coefficients. They are thus ideal
for most industrial or general purpose
displacement measurement applications.
