Energy Accelerometers
Ruggedized Solutions for Demanding Downhole Sensing
Honeywell’s Energy Q-Flex Accelerometers consist of the QAT160, QAT185 and the Mini Q. Our family of ruggedized acceleration sensors are designed and built to tolerate demanding measurement-while-drilling (MWD) and wireline environments while providing precision accuracy. Two models are available with different temperature ranges, allowing for flexibility in selecting the appropriate acceleration sensor.
Two models are available with different temperature ranges, allowing for flexibility in selecting the appropriate acceleration sensor. For a small diameter application we offer up the Mini Q. Please contact Honeywell for more information on this part.
Features
- Two temperature ranges
- Field scaleable
- Square and round flanges available
- Form and fit compatibility
