0 to 1 psi through 0 to 100 psi Pressure Transducers APPLICATIONS Medical Instrumentation Barometry HVAC Controls Pneumatic Controls FEATURES Piezoresistive Sensor Precision ASIC Conditioning High Level Output Temperature Compensated This ASDX series is an amplified version of SenSym ICT’s proven performer and industry leading SDX series sensor. This amplified ASDX device is in a package with the slightly larger footprint as the SDX but it offers a high level (4.0 V span) output on a very cost effective basis. This family is fully calibrated and temperature compensated using an on-board ASIC. These sensors are intended for use with non-corrosive, non-ionic working fluids; such as air and dry gases. Devices are available to measure absolute, differential, and gage pressures from 1 psi (ASDX01DN) through 100 psi (ASDX100). 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 gage or differential measurements. All ASDX devices are accurate to within +/- 2.0%. The devices are characterized for operation from a single 5 volt supply. The sensor is designed and manufactured according to standards laid down in ISO 9001.

Output is ratiometric within the supply voltage range (Vs). Note 2: 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. Note 3: 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.
