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 currentoutput 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.

For high-temperature Q-Flex® technology in a ruggedized package, Honeywell produces the QA-T160 and QA-T185 models for down-hole measurement-whiledrilling and wireline applications. As with the entire Q-Flex accelerometer family, QA-T160 and QA-T185 feature a patented Q-Flex etched-quartzflexure seismic system. An amorphous quartz proofmass structure provides excellent bias, scale factor, and axis alignment stability.
