| RBA Series Signal conditioned pressure sensors FEATURES * 0...10 inch H2O to 0...100 psi, 0...5 inch H2O to 0...100 psi, absolute, gage or differential pressure * 0.5...4.5 V ratiometric output * Precision ASIC signal conditioning * Temperature compensated * Sensortechnics PRO services MEDIA COMPATIBILITY To be used with non-corrosive, non-ionic working fluids such as clean dry air, dry gases and the like. SPECIFICATIONS Maximum ratings Supply voltage VS max. 6.50 VDC Output current Sink Source Lead temperature (2 - 4 sec.) Temperature ranges Compensated Operating Storage Vibration Shock RBAP... RBAH... Caution! The sensors are not reverse polarity protected. Incorrect applications of excitation voltage or ground to the wrong pin can cause electrical failure. Application of supply voltage above the maximum can cause electrical failure.

If maximum burst pressure is exceeded, even momentarily, the package may leak or burst, or the pressure sensing die may fracture. 2. Full Scale Span (FSS) is the algebraic difference between the output signal for the highest and lowest specified pressure. Span is ratiometric to the supply voltage. 3. Total accuracy is the combined error from offset and span calibration, linearity, pressure hysteresis, and temperature effects. Linearity is the measured deviation based on a straight line. Hysteresis is the maximum output difference at any point within the operating pressure range for increasing and decreasing pressure. Calibration errors include the deviation of offset and full scale from nominal values. 4. Delay time between sampling and signal change at the output. 5. The smallest change in the output voltage, given any change in pressure. 6. This is the maximum temperature shift for offset when measured between 0...85 C relative to the 25 C reading.
