AC operation from 2kHz to 20kHz
Stainless steel housing
Imperial or metric threaded core
The legendary MHR Series LVDTs provide precision
measurements in space restrictive applications. With a
diameter of just 3/8 inch [9.5mm], and an extremely
lightweight core, the MHR Series is ideal for applications
where excessive core weight could influence the motion;
with less inertia, accurate measurements at higher
displacement speeds are easier to achieve. The
lightweight core also reduces mechanical stresses and
helps preserve the structural integrity of the core
actuation assembly.
The high output sensitivity resulting from the close
electrical coupling between the coil and core provides
ample signal for interfacing with practically all signal
conditioners and conditioning circuits. The magnetic
stainless steel housing provides electromagnetic and
electrostatic shielding.
The high temperature operation (200oC) model, MHR-T
is available for stroke ranges of ±0.025 to ±1 inch. A High
pressure (vented case) model, MHR-V is also available.
The MHR is compatible with the full line of Measurement
Specialties LVDT signal conditioners.
Like in most of our LVDTs, the MHR 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.
