DCXL-DS Series
SURSENSE™ Ultra Low
Pressure Sensor
Silicon Pressure Sensors
DESCRIPTION
The SURSENSE line of ultra low pressure sensors is
based upon a proprietary technology designed to reduce
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.
FEATURES
The DCXL-DS Series provides a precision calibrated,
ratiometric mV output with SURSENSE-enhanced
stability. Each sensor features calibrated offset, full scale
span and thermal error calibration to promote 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. The housing design incorporates a
snap together cover and housing leading to improved
quality and performance.
Product is patented by US patent 6023978.

MEDIA COMPATIBILITY (wetted materials)
Ports 1 and 2: Dry gases only. Media must be
compatible with epoxy-based adhesive, silicon,
silicone, gold, nylon and alumina.
PRESSURE COMPATIBILITY
Measures differential or gage pressure and vacuum.
Pressure may be applied to either port. For pressure to
the low pressure port, the output polarity is reversed.
RATIOMETRIC OUTPUT
The output voltage of the sensor is ratiometric
(proportional) to the excitation voltage. All specifications
will change proportionally to any changes in the excitation
voltage, which may vary between 3 Vdc to 16 Vdc. All
specifications will nominally be changed by a ratio of
V Excitation/12.0 Vdc. For example: if the excitation
voltage is 5.0 Vdc, then both the full scale output voltage
and the offset voltage nominal would be 5/12th the
specified value.
