  • GEMS™ SENSORS & CONTROLSLIQUID LEVEL SENSING TECHNOLOGIES Website: www.GemsSensors.com Call : 1-800-378- 1600
  • VARIOUS TECHNOLOGIES…..Each of today’s liquid level sensing technologiesexcels in various roles and primarily includes thefollowing types:• Float or Buoyancy • Pressure• Conductivity • Load Cells• Capacitance • Piezo Resonant• Ultrasonic • Optical Website: www.GemsSensors.com Call : 1-800-378- 1600
  • FLOAT/BUOYANCYPros: Non-powered, proven, direct indicationCons: Invasive, contact fluids, moving partsTypical Applications: Water Tanks, saline, buffer,and reagent bottle content monitoringCONDUCTIVITYPros: No moving parts, low costCons: Invasive, probe erosion, liquid needs to beconductiveTypical Applications: Boiler water, reagentmonitoring Website: www.GemsSensors.com Call : 1-800-378- 1600
  • CAPACITANCEPros: No moving parts, can be non-invasive,accurateCons: Continuous calibration, needs resistive liquidsTypical Applications: Reagent, waste, and washcontainer levelsULTRASONICPros: No moving parts, small, accurateCons: Expensive, invasiveTypical Applications: Large process tankspharmaceutical Website: www.GemsSensors.com Call : 1-800-378- 1600
  • PIEZO-RESONANTPros: Non-invasive/non-contact, accurate, repeatable,and economicalCons: Powered, works only with plastic containers,wall thickness, temperature limitationsTypical Applications: Reagents, waste, diluents, wash,saline, pure water ExOsense Piezo-Resonant Sensor Website: www.GemsSensors.com Call : 1-800-378- 1600
  • ELECTRO-OPTICALPros: Compact, no moving parts, high temperaturecapabilityCons: Invasive, powered, and can be affected by dryor coating mediaTypical Applications: Reagents, waste, dialysate,detergent/wash, and coolant Website: www.GemsSensors.com Call : 1-800-378- 1600
  • ELECTRO-OPTIC OPERATING PRINCIPLE•Contains an infrared LED and a light receiver•Light from the LED is directed into a prism which forms the tip ofthe sensor•With no liquid, light from the LED is reflected within the prism tothe receiver•When liquid immerses the prism, the light is refracted out into theliquid, leaving little or no light to reach the receiver•Sensing this change, the receiver actuates electronic switchingwithin the unit to operate an external alarm or control circuit Website: www.GemsSensors.com Call : 1-800-378- 1600
