SPECIFICATIONS
High Reliability
Large core-to-bore clearance
Stroke ranges from ± 0.05 to ±10 inches
AC operation from 400Hz to 5kHz
Stainless steel housing
Imperial or metric threaded core
Many options and accessories
The HR Series general purpose LVDTs provide the
optimum performance required for a majority of
applications. The large 1/16 inch [1.6mm] bore-to-core
radial clearance provides for ample installation
misalignments and therefore reduces the application
costs. Featuring a high output voltage and a broad
operating frequency range, these versatile and highly
reliable LVDTs deliver worry-free and precise position
measurements.
Available in a variety of stroke ranges from ±0.05 to ±10
inches, the HR Series can be configured with a number
of standard options including guided core, small
diameter/low mass core. High temperature (200ºC)
operation and Mild Radiation Resistance versions are
also available (consult factory). The HR Series is
compatible with the full line of Measurement Specialties
LVDT signal conditioners.
Like in most of our LVDTs, the HR windings are vacuum
impregnated with a specially formulated, high
temperature, flexible resin, and the coil assembly is
potted inside its housing with a two-component epoxy.
This provides excellent protection against hostile
environments such as high humidity, vibration and
shock.
