Details

The L3515 is composed of an electronics unit housed in a heavy-duty, cast aluminum, weatherproof and explosion proof enclosure, and an integrally mounted sensor flange. The L3515 is provided with a continuously adjustable 0 to 30 second time delay to avoid unnecessary shutdowns due to momentary voids which might appear in the process stream.

The PRINCO L3545 is similar in operation to the L3515, except the L3545 has a remote mounted sensor flange, which may be located up to 3000 feet away from the electronics unit. They are connected by means of an ordinary multiconductor (not coaxial) cable. A remote override (startup) feature is also provided. Reliable protection is thus available for applications where equipment must be located in inaccessible areas.
