MarineGrade™ Sensors: Built for Shipboard Demands

Marine Fluid Level Control Sensors – Gems™ Sensors

Since 1955, Gems™ Sensors & Controls has earned a solid reputation for accuracy and dependability in marine service. 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 Vibration...Inclination, Bureau Veritas, Lloyds, ABS and USCG. Commercial vessel approvals include UL, CSA, and FM.

Typical applications are ship-wide and include high, low and/or intermediate level alarms, automatic pump-up and pump-down control, single-point, multi-point and continuous level monitoring, flow confirmation, and pressure switch monitoring in:

  • Auxiliary generator fuel tanks
  • Bilge level detection
  • Fuel oil storage tanks
  • Potable water storage tanks
  • Deck flooding alarms
  • Ballast tanks
  • Hydraulic system reservoirs
  • Gray water tanks
  • Cooling systems
  • Coolant tanks
  • Bilges and Voids
  • AFFF Tanks
  • Day tanks
  • High level alarms for closed loading
  • Lube oil and lube sump tanks

Gems 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.
