Microminiature Gauging Displacement Sensor
Designed specifically for tight spaces, the Microminiature
Gauging DVRT® delivers high performance in a tiny package.
A sapphire bearing and ruby ball guide the spring-loaded tip,
providing an exceptionally smooth static and dynamic
response. The Microminiature Gauging DVRT® features
micron-to-sub-micron resolution, linear analog output, flat
dynamic response to kHz levels, and very low temperature
coefficients. Extremely lightweight, captive cores are tiny yet
rugged. Superelastic, corrosion-resistant alloys provide
resistance to kinking and permanent deformation, and allow
complete submersion of the instrument

Dimensional Gauging for Quality Control
Core position is detected by measuring the coils’ differential
reluctance using a sine wave excitation and synchronous
demodulator. This differential detection method provides a
very sensitive measure of core position while cancelling out
temperature effects.
The transducers’ coils and Teflon® cables are sealed in
vacuum-pumped epoxy, within the stainless-steel case. This
provides outstanding environmental resistance. The DVRT®
has been successfully employed in harsh applications,
including short term immersion in saline and pressurized oil.
Units available for long term immersion, corrosive and high
pressure environments can be custom built to meet such
requirements. LORD MicroStrain®’s desktop consoles and
in-line signal conditioners provide the Microminiature Gauging
DVRT® with plug and play housing, power, analog output,
LCD display, RS-232 output and software. A range of
modular positioning attachments and custom strokes are also
available.
