DESCRIPTION
The SURSENSE™ line of ultra low pressure sensors is based
upon a proprietary, patent applied for technology designed
to reduce all output offset or common mode errors.
These sensors utilize 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 DCAL series sensors provide a precision calibrated
ratiometric 4 -volt output with SURSENSE enhanced stability.
Each sensor features the precision calibration found in the
DCX series with the addition of fully integrated signal
conditioning in an industry standard package. Intended to
operate from a fixed 5Vdc supply, the DCAL4 gage pressure
sensors provide a 0.25v to 4.25v output while the differential
versions provide a ±2.0 volt output centered on a 2.25 volt
zero pressure offset. These highly stable sensors are ideally
suited for microprocessor or microcontroller based systems.
