Level Switches For Use In 55-Gallon Drums Available In 3 Versions From GEMS

GEMS Express Service now offers convenient level switches to fit a 3/4-inch bung fitting on 55-gallon drums. Three versions are available for normal six to eight weeks' delivery.

The high- and low-level model features two floats in a single unit for monitoring both high and low levels. Separate, single-float units for low-level and high-level use are also offered.

The units feature simple opera- 1 tions: a magnet-equipped float, moving directly with the liquid level, actuates a hermetically sealed switch within the unit's stem. When combined with GEMS relays, they can operate remote pumps and other equipment.

These switches withstand pressures to 100 psig and temperatures to 180 degrees F. Pilot duty rating is 20 VA, 120-240 VAC.

Used with GEMS annunciator cubes, the status of four switches can be read simultaneously from a single unit. Or, up to five switch closures can be monitored using a GEMS panel indicator.
