DUXL Series SursenseTM Ultra Low Silicon Pressure Sensors DESCRIPTION The DUXL Series sensors provide a ratiometric millivolt output The SURSENSETM line of ultra low pressure sensors is based and are housed in a low profile miniature ported package. upon a proprietary technology designed to reduce all output These sensors are intended for those applications where offset or common mode errors. customized external signal conditioning is required or available from other sources. The low profile outline is ideal for portable These sensors use a silicon micromachined sensing element applications where small size is critical. which features a unique stress concentration enhanced structure to provide a highly stable linear output that is Product is patented by US patent 6023978 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 POTENTIAL APPLICATIONS * Position sensitivity to 5 mV/g, typical * Hand held instrumentation * Operating temperature range -25 C to 85 C * Airflow controllers [-13 F to 185 F] * Medical monitors Available in gage and differential pressure ranges * Smart microvalves and switches * Level indicators * DUXL Series ELECTRICAL SPECIFICATIONS (At 4.5 Vdc Excitation 25 C [77 F].)

The voltage added to the offset voltage at full scale pressure. Nominally the output voltage range is 1.0 Vdc to 6.0 Vdc. 2. Shift is relative to 25 C [77 F] 3. Measured at 1/2 full scale operating pressure using BFSL 4. Shift is within the first hour of excitation applied to the device.
