Gun Barrel Bore Gauges

ABOUT

BG10 Gun Barrel Bore Gauge System

The BG10 Gun Barrel Bore Gauge System is an electro-mechanical measuring device that was originally introduced into service by the RAF for the high-speed measurement of aircraft cannons, to ensure minimum operational aircraft turnaround time. Measurements are taken at 16 pre-determined positions along each bore, which are then compared to pre-stored warning and rejection criteria. The actual measurements taken are displayed to the Operator on an LCD display and the measurements stored for future reference. The system will automatically provide a visual indication on the Hand Held Unit whether the barrel was acceptable, close to tolerance or rejected – all this to be undertaken in less than five minutes!

BG20 Large Calibre Barrel Bore Gauge System

The BG20 has been specifically designed to modernise and improve the inspection routines of large calibre barrels. A two-point measuring head is supported in the barrel or chamber by a clear disk which facilitates the angular alignment of the head and the location of a suspected defect.

The gauge may be introduced into the breech or muzzle end of the barrel and the measuring head located anywhere along its length. Any number of measurements may be taken and will be automatically stored under the barrel identification that is entered by the Operator. The measuring process can be effected in minutes.

The operating software of the gauge provides the flexibility to automate existing in-service measurement routines or to accommodate specific defect investigations such as barrel bulging or ovaling.

Both the BG10 and BG20 Bore Gauge Systems are provided in rugged carrying cases affording protection, storage and ease of transportation.
