High Temperature Precision Accelerometer Compact Design For Energy Exploration

Precision Accelerometers for Energy Exploration

Description

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
