Paddle type level switches

ML-D1 series
ML-D1 series
This is definitely the model of paddle level sensors that will give you stable powder level detection for a long time

Can detect almost all powder and granulated material stably.Its unique mechanism allows long term, stable detection of powder levels. These paddle switches were designed to be compact and cost less than conventional models.
A two-layered seal system and Mum design are employed to prevent powder and granulated materials from getting inside the housing.
*A 24DC model has obtained the CE marking.

  • 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..


Features, keys

  1. Uses a 2-layer sealed construction
    Securely prevents the intrusion of powder and granulated material thanks to an oil seal plus a 2-layer oil seal.
  2. Prevents the entrance of powder and granulated materials into the case.
    A mum-structured sintered alloy bearing prevents leaks from the seals.
  3. Gear drive system
    Can be reduce teh failure because shaft and motor is not directly connected.
  4. Employed the slip mechanism
    The slip mechanism softens shocks to the vanes and shaft.
  5. The inside the paddle level sensor can be detached so that it is easy to check.
  6. Fine torque adjustment
    Torque can be finely adjusted by the stepless static torque adjustment function.
  7. 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.
  8. Obtained the CE marking
    A 24VDC model has obtained the CE marking.
