High Temperature Accelerometers Based On Q-Flex® Technology
Honeywell produces the QAT (160C and 185C versions) and the MiniQ (150C, 185C and 200C) high temperature accelerometers for down hole measurement-while-drilling and wireline applications. These accelerometers utilize Honeywell’s Q-FLEX® design,
the industry standard in Aerospace,
QAT 160 QAT 185 Mini Q
Features
ruggedized for high temperature use.
As with the entire Q-Flex accelerometer family, the QAT and MiniQ accelerometers feature 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 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.
Honeywell’s energy accelerometers 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
