"Smart" Magnetic Fluid Level Sensor

Magnetic Technology - Patent pending.

Standex Electronics has developed a magnetic technology based Fluid Level Sensor series that allows external electronics to perform a full diagnostic routine every time a vehicle is started, or any time during normal operation as desired. The sensor is suitable for use in applications for brake fluid, coolant, washer fluid and oil level sensing. Contained within the sensor is a wound element located near the magnetic switch that will allow the magnetic switch element to be actuated remotely while the external electronics monitors the condition (output) of the switch.

  • Normally operates with separate float/magnet assembly.
  • Capable of providing real time conformation of proper sensor operation.
  • Capable of providing operation information every time vehicle is powered up.
  • Provides safety critical information for fluid levels such as brake fluid.
  • Provides important information for fluid levels where absence of fluid could bring costly repairs - such as with coolant or oil.
  • Capable of providing complete fluid level system operation information during fluid container assembly process.
  • Relatively low system cost impact.
  • Requires third wire to sensor assembly.
