The LC30 surge protection device protects load cell and weighing system installations from possible malfunctions or damage to individual strain-gauge bridges of associated electronic instrumentation etc. caused by severe over voltages or impulse currents on signal cabling.

It protects load cells, weighbridges, process weighing and silos Surge protection devices protect the system at the point of installation; therefore a full system is likely to have at least one LC30 device installed at the weighbridge to protect the load cell(s), and another LC30 in the weighing control cabin to protect the electronics installed there. The advanced protection concept used in the LC30 also eliminates the expensive additional earthling systems specified by other suppliers, so field installation is very simple indeed.
