q-flex ? QA-1400 accelerometer cost-effective inertial-grade sensor for the most cost-effective inertial-navigation grade solution, honeywell produces the qa1400 for a variety of industrial and laboratory applications. as with the entire q-flex family of accelerometers, the qa1400 features a 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. the qa1400 also includes a current-output, internal temperature sensor. by applying temperature-compensating algorithms, bias, scale factor, and axis misalignment performance are dramatically improved. implementation of the thermal modeling results in bias residual errors as low as 200 g and scale factor errors as low as 400 ppm. features ? excellent turn-on composite repeatability and stability performance ? environmentally rugged ? analog output ? field-adjustable range ? three fastener precision mounting flange ? internal temperature sensor for thermal compensation ? dual built-in test ? selectable bias temperature sensitivity configuration drawings
