GEMS Level Switches for

Shipboard Service.

Where high reliability is required for monitoring liquid levels and signaling alarms.

There's a GEMS switch to meet all types of marine liquid level applications...to monitor and control levels, signal alarms, and to provide oil/water interface. Ideal for use with diesel engine fuel tanks, lube oil reservoirs, ballast, bilge, or oil sump tanks or for other common shipboard uses. 3= 1 58000 Series

Single or Multi-Level

Switches.

Custom-made switches, using standard components, are supplied with various mounting methods, lengths, floats, materials, etc. to suit the application. 9

LS-35565 (brass)/

LS-56060 (stainless steel) Externally

Mounted Models.

For use where access to inside of tanks is limited, such as on lube oil or fuel day tanks. Custom-length housings. Provide ease of maintenance and tank cleaning

LS-270 Model with Protective

Shielding for

Turbulent In-Tank

Conditions.

Small and com- pact. unit side- mounts in tank.

Ideal for low level bilge or sump tanks, and oil/ water interface

With Intrinsic Safety.

Zener Barrier Safe-Pak relays, FM approved, from

GEMS provide intrinsically safe operation when interfacing level switches with your AC or DC loads.

We build them.

We fix them.

And we do it on schedule.

We overhauled the 793-foot USS SACRAMENTO ahead of schedule.

We built the 644-foot USS MCKEE under budget and ahead of schedule.

And at Lockheed Shipbuilding we do the same for more than a hundred ships, large and small, every year.

We've got floating dry docks to 14,500 tons, shipways to 700 feet, and piers to 1,100 feet.

And, we've got the superior craftsmen it takes to do your job.

So if your ship needs a new propulsion system, or just a "shave and a haircut," call us. We do superior work. And you won't have to wait long for it.

Superior ships by superior workers
