honeywell QA-T160 and qa-t185 accelerometer high temperature energy sensors for high-temperature q-flex? technology in a ruggedized package, honeywell produces the QA-T160 and qa-t185 models for down-hole measurement-while- drilling and wireline applications. as with the entire q-flex accelerometer family, QA-T160 and qa-t185 feature a patented q-flex etched-quartz- flexure seismic system. an amorphous quartz proofmass structure provides excellent bias, scale factor, and axis alignment stability. the integral q-flex electronics develop 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 QA-T160 and qa-t185 also include a current- output internal temperature sensor. by applying temperature-compensating algorithms, bias, scale factor, and axis misalignment performance are dramatically improved. robust design and quality assurance provides superior reliability. features ? high temperature capability ? environmentally rugged ? analog output ? square or round mounting flange options ? field-adjustable range ? internal temperature sensor for thermal compensation ? low power electronics ? built-in test accelerometers exported from the united states must be done in accordance with the export administration regulations (ear) and/or the international traffic in arms regulations (itar) as applicable. exp032, april 2004 configuration drawings
