Honeywell QA-T160 QA-T185 Accelerometer ±20g High Temp Sensor

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.
