WARNING
PERSONAL INJURY
DO NOT USE these products
as safety or emergency stop
devices or in any other
application where failure of the
product could result in
personal injury.
Failure to comply with these
instructions could result in
death or serious injury.
The DCXL 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 DCXL Series sensors provide a precision calibrated ratiometric
millivolt output using the enhanced stability of SURSENSE technology .
Each sensor features calibrated offset, full scale span and thermal error
calibration to ensure the highest possible accuracy for flow pressure
measurement. These highly stable sensors feature an industry standard
ported package with improved stress isolation for printed circuit board
mount applications.
Product is patented by US patent 6023978.
