Silicon Pressure Sensors Ultra Low Pressure Sensing DC Series FEATURES • Ultra Low Pressure Sensing, down to 2.5 mBar • ASIC Technology • Available in Gage and Differential Pressure Ranges • Available in Ratiometric and Regulated • Temperature Compensated over 0 °C to 50°C [32 °F to 122 °F] • Combined Linearity and Hysteresis error < ±0.25 % Span TYPICAL APPLICATIONS • Medical Instrumentation GENERAL DESCRIPTION • HVAC The DC Series pressure sensors combine SURSENSE™ precision high Environmental Controls sensitivity silicon sensing capabilities with the latest in Application Specific • Portable Monitors Integrated Circuitry ASIC technology to produce one of the most precise, reliable pressure sensors in the market. The SURSENSE technology provides Dynamic Self Compensation which substantially reduces offset errors due to changes in temperature, stability to warm up, long term instability and position sensitivity. When operated with an unregulated 7.0 Vdc to 30.0 Vdc supply the DC sensors provides a ratiometric 0.50 to 4.50 Vdc output (4.0 Vdc span).
