signal conditioned pressure sensors 0 -1 psi to 0 - 150 psi ascx series features calibrated & temperature compensated 4.5 volt span ? v olt supply small size absolute & differential (gauge) pressures reliable semiconductor t echnology typical applications industrial controls medical equipment pneumatic controls electrical connection this series is an amplified version of sensym s proven performer and industry leading scx series sensor. this amplified ascx device is in a package with the same footprint as the scx but it offers a high level (4.5 v span) output on a very cost effective basis. this family is fully calibrated and temperature compensated. 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 gauge pressures from 1 psi (ascx01dn) through 150 psi (ascx150dn). 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 ascx devices are calibrated for span to within +/- 1%. the devices are characterized for operation from a single 5 volt supply although sensitivity is ratiometric to the supply voltage and any dc supply from 5 to 16 volts is acceptable. contact your local sensym ict representative, the factory, or go to sensym ict s web site at www.sensym-ict.com for additional details. automation and control products ? honeywell 2002, all rights reserved 12 3 4 56 pin 1: external offset adjust pin 2: vs pin 3: + output pin 4: ground pin 5: n/c pin 6: n/c w arning personal injury do not use these products as safety or emergency stop devices or in any other application where failure of the product could result in personal injury. failure to comply with these instructions could result in death or serious injury. w arning misuse of documentation ?the information presented in this product sheet is for reference only. do not use this document as a product installation guide. ?complete installation, operation, and maintenance information is provided in the instructions supplied with each product. failure to comply with these instructions could result in death or serious injury. ! !
