The Crouse-Hinds series 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, caused by severe overvoltages or impulse currents on signal cabling.
Fully solid state, the LC30 clamps incoming surges immediately without causing undue leakage losses under normal conditions. Once the surge has passed, the device automatically resets to the passive state, allowing normal operations to continue.
The advanced protection concept used in the LC30 also eliminates the expensive additional earthing systems specified by other suppliers so field installation is very simple indeed. The LC30 device is non-voltage producing, non energy storing ‘simple apparatus’ and as such, can be used in hazardous areas with appropriate self generated system documentation. The LC30 is also certified for use in legal metrology applications.
