q-flex ? QA-750 accelerometer cost-effective inertial-grade sensor for q-flex technology in an economical package, honeywell produces the qa750 for a broad array of moderate performance applications. as with the entire q-flex family of accelerometers, the qa750 features patented q-flex? etched-quartz-flexure seismic system. an amorphous quartz proof-mass structure provides excellent bias, scale factor, and axis alignment stability. the integral electronics develops an acceleration proportional output current providing both static and dynamic acceleration measurements. by use of a customer supplied output load resistor, appropriately scaled for the acceleration range of the application, the output current can be converted into a voltage. as an option, the qa750 can be provided with the temperature-compensating algorithm where bias, scale factor, and axis misalignment performance are dramatically improved. robust design and quality assurance provides superior reliability. features ? high value ? environmentally rugged ? analog output ? compact design ? field-adjustable range ? built-in test ? optional thermal compensation configuration drawings .625 (15.88) .264 (6.71) .566 (14.38) 1.132 (28.75) ? 1.50 max (38.1) 3x r1.82 @ 120 (46.2) 3x r1.34 @ 120 (34.0) 6x .100 ? 1.010 (25.65) max ? 1.00 (25.4) max 3x .130 (3.30) max .780 (19.81) max 3x ? .136 (3.45)
