Specified to 175-degree Celsius operation, the ±2,000°/sec

NORWOOD, Mass. -- (Business Wire)
Analog
Devices, Inc. (NASDAQ: ADI) today introduced the first and only MEMS
gyroscope specified to withstand temperatures of up to 175 degrees
Celsius commonly encountered by oil and gas drilling equipment.
The ADXRS645 MEMS (micro-electromechanical) gyroscope provides excellent
vibration immunity and a minimum rotational measurement range of
±2,000°/sec, which are critical performance criteria for drilling tools
operating in harsh, high-temperature environments. The ability to
accurately sense angular rotation prevents drill string damage by
detecting the difference between drill head rotation and the motor
turning the drill. The ADXRS645 allows rig operators in the oil and gas
industries to extend the life of their equipment and reduce costly
downtime by ensuring that the drill string is operating properly.
The ADXRS645 joins ADI’s portfolio of precision
high-temperature components designed for drilling applications,
including the ADXL206 ±5g precision MEMS accelerometer, the AD8229
ultra-low-noise instrumentation amplifier, the ADR225 2.5-V band gap
voltage reference and the AD8634 dual amplifier with rail-to-rail
outputs, all of which are specified to operate at 175 degrees Celsius
and higher.
The down-hole drilling industry is adopting a multitude of sensors to
better understand the motion of the drill string below the surface to
better optimize operations, prevent drill damage, and increase
productivity. Other approaches to rotational measurement, such as the
use of magnetometers, are susceptible to drill vibration, are unable to
precisely capture fast-changing rotational speeds and their readings can
be impacted by ferrous material or metal casings used in the well.
More About the ADXRS645 MEMS Gyroscope
The ADXRS645 features
low, 5-V single-supply operation and is the only MEMS gyroscope to
operate at up to 175 degrees Celsius for a minimum of 1,000 hours of
operation. Its unique ceramic vertical-mount package allows the device
to be robustly mounted to the PCB and eliminates the need for an
orthogonally-mounted daughtercard.
