The SBS ring type acoustic emission sensor, or Ring AE sensor, enables installation very close to the work-zone, eliminating the need for the AE signal to pass through bearings & joints. This is useful for internal grinding applications with no work-support, vertical grinding machines & for dual-support rotary diamond dressers.
