Silicon Sensing Upgrades Gyro for Downhole Surveying Image courtesy Silicon Sensing Silicon Sensing Systems is delivering its latest generation of gyroscopes, as the new CRS39A has been designed for use in severe environments including downhole drilling operations. This upgrade of Silicon Sensing’s established CRS39 gyro includes a move to a single board from two. This has reduced the unit’s mass by 40% and allows it to be installed far more easily in space-limited applications, such as the 25mm diameter cylinders typically used in downhole drilling equipment. CRS39A also incorporates ...
