The Anyload LA2 is a stainless steel lightning arrester designed to protect load cell systems and weighing electronics from lightning strikes and transient voltage surges. Equipped with gas discharge tubes and rated for a nominal impulse discharge current of 10 kA (8/20 μs), it features an IP66-sealed enclosure and must be firmly grounded to divert voltage spikes safely to ground.
The LA2 lightning arrester is an essential protective accessory for any weighing system installed in environments exposed to lightning, power surges, or transient voltage events. Electrical disturbances — whether from direct lightning strikes, nearby strikes, or switching surges on power lines — can instantly destroy sensitive load cell electronics and signal conditioners. The LA2 addresses this risk to protect expensive equipment.
The LA2 is wired in-line between the load cell(s) and the weighing indicator or junction box, making it straightforward to integrate into new installations or retrofit into existing systems. Its stainless steel housing withstands harsh outdoor and industrial environments, while the IP66 rating ensures reliable performance even in wet or dusty conditions. A dedicated ground wire connects the enclosure to earth ground — a mandatory connection for the protection system to function correctly.
Most Common Applications: Outdoor tank and silo weighing systems, truck scales, remote field deployments.
