Micro-Measurements Linear Displacement Sensors use a
fully active 350-ohm strain-gage bridge to sense spindle
displacement, giving infinite resolution and excellent
linearity. They are compatible with all standard strain-gage
instrumentation with bridge excitation from 2 to 10 volts. With
a selection of models having full-scale ranges from 1/4 in [5
mm] to 4 in [100 mm], Linear Displacement Sensors feature
a unique design that produces maximum operating forces of
less than 1 lb [4.4 N]. Available with specially designed
mounting fixtures, these versatile sensors are ideally suited
for us in research, manufacturing and process control
applications.
Accuracy
Micro-Measurements Linear Displacement Sensors produce
an output voltage proportional to a captive, guided spindle
displacement by means of a 350-ohm strain gage bridge with
four active arms. This arrangement provides excellent
temperature compensation and linearity.

Compatibility
Micro-Measurements Linear Displacement Sensors exhibit
the same inherent advantages for linearity, versatility and
precision as many other strain-gage-based sensors. As
such, they are systems-compatible with a wide range of
commonly used sensors for pressure, load, acceleration,
vibration, etc. and normally utilize the same instrumentation.
