HR Series – General Purpose LVDT
HR-Series Rev. 6 www.meas-spec.com 2015-July
1/4
• 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
DESCRIPTION
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 conf igured with
a number of st andard options including guided core, small diameter/low mass cor e. 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 condit ioners.
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.
Measurement Specialties, Inc. (NASDAQ MEAS) offers many other types of sensors and signal
conditioners. Data sheets can be downloaded from our web site at: http://www.meas-

MEAS acquired Schaevitz Sensors and the SchaevitzTM trademark in 2000.
