The DUXL line of ultra low pressure sensors is based upon
®
SURSENSE , a proprietary technology, which reduces all output offset or
common mode errors.
These sensors use a silicon, micromachined sensing element which
features a unique stress concentration enhanced structure to provide a
highly stable linear output that is proportional to applied pressure. Output
offset errors due to changes in temperature, warm-up, long term stability
and position sensitivity have all been significantly reduced when compared
to conventional sensors.
The DUXL Series sensors provide a ratiometric millivolt output and are
housed in a low profile miniature ported package. These sensors are
intended for those applications where customized external signal
conditioning is required or available from other sources. The low profile
outline is ideal for portable applications where small size is critical.
Product is patented by US patent 6023978.
