Product Details
HoneywellQA-T160 and QA-T185 Accelerometer
Description
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.
