Float Type Level Switch

Liên hệ

Level switch that uses buoyancy of a float to detect liquid level in a tank or container. Please use with liquids such as water, oil, and chemical solutions.

Brand: Matsushima
Origin: Japan


  1. Multi-contact level measurement can be constructed at low cost.
  2. It is not affected by the electrical characteristics (capacitance, conductivity, etc.) of object to be measured.
  3. SUS304, SUS316, PVC, and PP materials can be selected and can be used in corrosion-resistant environments.
  4. By using a reed switch, it is less susceptible to effects of temperature, humidity, gas, etc., achieving stable detection.
  5. It can also be used in sites where explosion-proof type (d2G4) is required.


  • Detect up to 4 points with one device!
  • Adopts reed switch
  • No power required.
  • Explosion-proof compatible

Operating principle

A float with a built-in magnet moves up and down according to liquid level, and reed switch built into main body is turned on and off by magnetic force.

How to use?

  1. Mounting position-1:

    Please install it in a place away from strong magnetic forces such as motors, transformers, solenoid valves, etc.
  2. Mounting position-2:

    Avoid using the product in areas with strong currents, such as inlet, outlet, locations that come into direct contact with water, and locations with agitators.
  3. Wiring:

    No power required. Please perform contact wiring.
  4. Adjustment:

    Detection position cannot be adjusted on site. Please specify detection position when ordering. It will be adjusted at the factory and shipped.
