A QWM weighbridge suffered only minor lightning damage from a recent electrical storm in south east Queensland.
The load cells fitted to QWM weighbridges are manufactured with in-built lightning protection to significantly reduce the chance of load cell damage during electrical storms.
To complement the load cell's resistance to lightning damage, QWM also fits surge arrestors within the junction boxes for added protection. The mounting hardware of each load cell is fitted with a heavy earth strap to help stray electrical current to bypass the load cells.
The digital weight indicator fitted to this quarry weighbridge was damaged by electrical current coming in via the serial output cable from an external device. Many later model digital weight indicators can be optionally fitted with opto-isolated serial ports to prevent this from happening.
QWM’s experienced service technicians quickly responded to the client’s request for urgent service and a replacement digital weight indicator was fitted. The weighbridge was then tested, calibrated and certified for trade use to allow the client to continue operating.
QWM is an Australian Owned manufacturer of heavy duty weighbridges and based in Brisbane. The company motto of "Made To Order - Built To Last" is fully backed by highly trained service technicians to ensure customer satisfaction.
