Micro Miniature Displacement Sensors.
The MicroStrain range of Micro-miniature displacement
sensors are so small that there is even one model with
only a 1.5mm full-scale range.
These tiny Differential Variable Reluctance Transducers (DVRT's)
are ideal for very small linear displacement measurements.
These sensors are available with standard stroke lengths of 3, 6
and 9mm, as well as the 1.5mm model with sub-micron resolution.
The outside diameter is just 1.5mm, and there are several
specialised mounting attachments available, including a barb
fitting for mounting in soft tissue. These sensors include a short
20cm lead out, fitted with a 4 pin keyed connector.
Other features include a linear analogue output, flat dynamic
response up to kHz levels, and very low temperature coefficients.
The free sliding 0.5mm diameter cores, are extremely lightweight
and utilize flexible biocompatible NiTi alloys to provide resistance
to kinking and permanent deformation.
Typical applications include tissue deformation, positioning of
optical components, virtual reality sensing and robotic systems.
Additional external signal conditioning modules provide the
required excitation and demodulation of the output signals,
providing either voltage or serial outputs.
