Microstructure Pressure Sensors 0 psi to 1 psi through 0 psi to 100 psi ASDX Series FEATURES * ASIC enhanced output * Wide compensated temperature range 0 C to 85 C [32 F to 185 F] * Available in absolute, differential and gage types * Pressure ranges from 0 psi to 1 psi through 0 psi to 100 psi * Accuracy 2 % max. Volts Full Scale * Quantization step of 3 mV * Response time 8 ms TYPICAL APPLICATIONS * Flow calibrators * Ventilation and air flow monitors * Gas flow instrumentation * Dialysis equipment * Sleep apnea monitoring and therapy equipment * Barometry * HVAC controls * Pneumatic controls The ASDX series is an amplified version of Honeywell's proven performer and industry leading SDX series sensor. The amplified ASDX sensor's footprint is slightly larger than the SDX but it offers a high level output (4.0 Vdc span) on a very cost-effective basis. This series is fully calibrated and temperature compensated with on-board Application Specific Integrated Circuitry (ASIC). They are intended for use with non-corrosive, non-ionic working fluids; such as air and dry gases. Sensors are available to measure absolute, differential, and gage pressures. The absolute devices have an internal vacuum reference and an output voltage proportional to absolute pressure. Differential devices allow application of pressure to either side of the sensing diaphragm and can be used for gauge or differential measurements. All ASDX devices are accurate to within 2.0 % full scale, designed for operation from a single 5.0 Vdc supply and are manufactured in accordance with ISO 9001 standards.

Pins 4, 5, 6, 7 and 8 are internal device connections and should not be connected to external circuitry or ground. If maximum burst pressure is exceeded, even momentarily, the package may leak or burst, or the pressure sensing die may fracture. Reference Conditions (unless otherwise noted): Supply voltage, VS=5.0 0.01 Vdc; TA=25 C [77 F]. Output is ratiometric within the supply voltage range (Vs). Span is the algebraic difference between the output voltage at the specified pressure and the output at zero pressure. Span is ratiometric to the supply voltage. Accuracy is the combined errors 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. Response time for a 0 psi to full-scale pressure step change, 10 % to 90 % rise time. The smallest change in the output voltage, given any change in pressure.
