Paddle type level switches

ML/GL series
ML-S7/GL-S7 series
Paddle level sensor with great result, high reliability, and long-term safe operation

Can detect almost all powder and granulated material stably. Its unique mechanism allows long term, stable detection of powder levels.
A two-layered seal system and Mum design are employed to prevent powder and granulated materials from getting inside the housing.

  • For powder

A variety of products available to meet a wide range of needs, from standard to special specifications. Standard flange types, resistant types, protection tube types, extension types, etc.. Pressure resistant explosion proof models are also available.


Features, keys

  1. Prevents the entrance of powder and granulated materials into the case
    A mum-structured sintered alloy bearing prevents leaks from the seals.
  2. Employed the slip mechanism
    The slip mechanism softens shocks to the vanes and shaft.
  3. The inside the paddle level sensor can be detached so that it is easy to check
  4. Fine torque adjustment
    Torque can be finely adjusted by the stepless static torque adjustment function.
  5. A variety of lines
    Lots of paddle type switches are available, including a type with a shaft protection tube, high temperature types, shaft extension types, and wire types.


ML-S7 series (no explosion proof type)

Line up of the ML series
* Above is an example from the line up.

GL-S7 series (pressure-resistant and explosion-proof type)

Can be installed in an explosion prevention areas
These switches can be used in hazardous areas containing flammable gases and vapor, and has a pressure-resistant, ad explosion-proof design (d2G4)
Two methods are used for leading lines into the terminal box from the outside
Connect wire conduits using pressure resistant threads or use a pressure resistant packing .
Uses a 4-layer sealed construction
Securely prevents the intrusion of powder and granulated material thanks to an oil seal plus a 4-layer oil seal.

Line up of the GL series
* Above is an example from the line up.
