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 The ASDX series is an amplified version of Honeywells proven performer Ventilation and air flow and industry leading SDX series sensor. The amplified ASDX sensors monitors footprint is slightly larger than the SDX but it offers a high level output (4.0 Gas flow instrumentation Vdc span) on a very cost-effective basis. This series is fully calibrated and Dialysis equipment temperature compensated with on-board Application Specific Integrated Sleep apnea monitoring Circuitry (ASIC). They are intended for use with non-corrosive, non-ionic and therapy equipment working fluids such as air and dry gases. Barometry HVAC controls Sensors are available to measure absolute, differential, and gage pressures. Pneumatic controls 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.
