Electrode Type Level Switch

Liên hệ

Electrode Type Level Switch is level sensor for detecting level of liquid. When electrode comes into contact with liquid, electrical circuit closes and switch operates.
Please use it for control, alarm, etc.

Brand: Matsushima
Origin: Japan


  1. Achieves multi-contact detection at low cost.
  2. Since there are no moving parts, it can be used stably for a long period of time.
  3. By cutting electrode part, detection position can be changed freely by the customer.
  4. It can be used with various liquids by changing material of electrode part.


  • Detect up to 6 points with one device!
  • Compatible with various liquids
  • Structure resistant to steam inside tank

Operating principle

Operating principle Electrode Type Level Switch are used in combination with relay units. The relay unit supplies a weak alternating current, so if surface of conductive liquid is not in contact with electrode rod, no current will flow to electrode, and when electrode rod touches liquid surface, current will not flow. It flows.

When current flows, the relay contacts open and close, informing you of detected and undetected areas.

How to use?

  1. Installation:

    Install electrode level switch vertically.
  2. Electrode connection:

    Pass separator (if electrode rod is over 1m), lock nut, and spring washer in this order. Loosen the set screw on the connector, screw the electrode rod into the center of the connector, and tighten the set screw again to secure it. After fixing, tighten the lock nut to prevent it from falling off.
  3. Ensuring continuity:

    When cutting the electrode rod to match the control level, remove 10mm of the coating from the tip to ensure continuity. (Above figure) (excluding ground electrode)

  4. Wiring:

    Please use electric wires of approximately 1.25sq. Use M3 screws with a pitch of 7 mm between terminals and crimp terminals.
    *Regarding relay unit, please prepare a product with current protection separately. (Recommended product: OMRON 61F series)
