QAT160/T185 Q-Flex®
Accelerometers

Honeywell's family of ruggedized Q-Flex® accelerometers are designed and built to tolerate demanding measurement-while-drilling (MWD) and wireline environments while providing precision accuracy. Years of downhole experience and an extensive test regime insure that our sensors exhibit superior reliability.

Two models are available with different temperature ranges, allowing the customer flexibility in selecting the appropriate sensor.

Features

  • Two temperature ranges
  • Field scaleable
  • Square and round flanges available
  • Form and fit compatibility
  • Internal temp sensor
  • Low Power
