Produced following extensive research and development effort by ASAMS the SYSTEM 12 underwater magnetic particle inspection unit has been developed as the ideal diver operated underwater MPI system for shallow watertidal water use. Discussions with inspection diving contractors revealed a requirement for a fully portable underwater MPI unit capable of being used by divers in shallow water or tidal conditions. Ideally the unit should NOT require any form of umbilical connection to the surface and should be capable of sustaining the inspection operation for up to 4 hours duration.
The result of this development is an inspection system powered from a 12 volt rechargeable battery unit and comprising battery control unit DC electromagnetic yoke and a high intensity UV light incorporating an arc discharge bulb for high ultraviolet content in the light produced. Magnetic ink can be supplied by attaching the optional ink dispensing unit or even from the surface.
The pressure housings for the battery-electronic control unit and the lamp are fabricated from anodised aluminium alloy and are pressure tested to a depth of 600 feet. A unique power-saving feature of the unit is that both the lamp and the DC electromagnetic yoke can be switched on-off by the diver. The electronic control system used for the gas discharge bulb in the UV lamp enables maximum UV output to be produced within 30 seconds of switching on the lamp and the electromagnetic yoke incorporates a sealed switch unit giving the diver full operational control.
In the event that the optional dispensing system is used the ink supply to the work piece can be incorporated into the handle of the UV lamp.
