Surge Suppression, LLC (SSI) products

Current loop surge protectors (surge protective devices) are used in industrial, manufacturing, and commercial facilities to measure speed, volume, weight, flow or other variables.  The current loop utilizes a continuous voltage with a varying current level that changes in direct proportion to the measured variable.  The vast majority of current loop units are 24 Vdc, 4-20 mA.  Other, non-standard voltages are available.
