Paddle type level switches
- 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.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
- Prevents the entrance of powder and granulated materials into the case
A mum-structured sintered alloy bearing prevents leaks from the seals. - Employed the slip mechanism
The slip mechanism softens shocks to the vanes and shaft. - The inside the paddle level sensor can be detached so that it is easy to check
- Fine torque adjustment
Torque can be finely adjusted by the stepless static torque adjustment function. - 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.
Line-up
ML-S7 series (no explosion proof type)
* 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.
Usages, use examples
Detects any type of powder (including upper and lower limits)
