Optic Rack Monitor Model 8130 for Bottom & Top Loading

Well-suited for bottom-loading applications with vehicles outfitted with Optic sensors, and also suited for overfill protection while top-loading railcars or tank trucks. Generates a unique, pulsed — and intrinsically safe — electrical signal that is transmitted to the sensors via a coiled cord and optic-format plug. When sensors on the transport are dry a signal is returned to the monitor. If the signal meets pre-determined characteristics the monitor goes to a “permissive” state, which changes the status light on the front of the 8100 Series Optic Rack Monitor from red (“non-permissive”) to green (“permissive”).
