Custom Engineered Single & Multi-Point Float Level Switches

From simple, high-volume reed switches to specialist technologies designed for more challenging environments, Gems Sensors & Controls offer an extensive choice of float-type level switches.
  • Hundreds of single and multi-point models
  • Specialist options for food use, ultra-pure liquids or hazardous chemicals
  • Can be custom designed or modified using 3-D modelling or integrated into subassemblies
The choice of optimum sensor is dictated by the media to be measured, such as its specific gravity, viscosity or corrosiveness. Sometimes, design constraints relate to the best way to integrate the sensor, including its position, mounting and size within a restricted space.Β
