The Rosemount 470 Transient Protector prevents damage from transients induced by lightning, welding, heavy electrical equipment or switch gears.
In laboratory simulated tests, this device withstood 2,000 amps or 10,000 volts without damage to either the transient protector or the transmitter. This protector continues to shield transmitters after repeated strikes (up to 5,000 amps) and is designed with a weatherproof, stainless steel-cased protector, enabling full operation in the most severe environments.
