Since 1955, Gems Sensors has earned a solid reputation for accuracy and dependability in military marine and commercial marine services. Gems Sensors marine products are approved and qualified to MIL-L-23886, the military specification for fluid level
sensors. Other military qualifications include MIL-S-901C, Shock Test High Impact Shipboard Machinery, Equipment and Systems…MIL-STD-167, Mechanical Vibration of Shipboard Equipment Vibration...Inclination, Bureau Veritas, Lloyds, ABS and USCG.
Commercial vessel approvals include UL, CSA, and FM.
Gems Sensors marine sensors are built purposefully rugged to accommodate harsh conditions including turbulent liquids, liquids containing foreign material, liquid interfaces, high
temperature and high-pressure fluids. Construction materials include bronze, 304 or 316 SS, Monel™ and copper-nickel alloys. Standard floats are of Buna N for oils, stainless steel for high temps, and Hycel (epoxy) for high pressures. Mounting
flanges and electrical connections per Navy specifications are routine at Gems Sensors & Controls.
For many years, the U.S. Navy has relied on the consistent accuracy and dependability of Gems switches in virtually every type of vessel, from surface to undersea. Gems marine products are approved and qualified to MIL-L-23886, the military specification for fluid level sensors. Other military qualifications include MIL-S-901C, Shock Test High Impact Shipboard Machinery, Equipment and Systems, MIL-STD-167, Mechanical Vibration of Shipboard Equipment, Inclination, Bureau Veritas, Lloyds, ABS and USCG.
Gems MarineGrade™ products have earned wide acceptance in the commercial marine industry. Commercial vessel approvals include UL, CSA, and FM. Gems engineers are very familiar with and experienced in the various aspects of shipboard requirements. Producing qualified sensor products to meet custom designs has long been our regular practice. With literally hundreds of these service-proven units documented on approved drawings, the solution to your fluid indicating problem is very likely a "standard" for us.
