Reversible Paddle Type Level Switch NNL/NNM Series

 
Unique mechanism eliminates mechanical wear parts inside the motor, which results in a long life and stability compared to conventional model! Suitable in processes with intense ON/OFF operations.
 

Features

 
  • Long life!
  • Special model withstandable against high-temperature and heavy load
  • As the internal mechanism is unitized, it can be replaced without removing the main body from the tank
  • A clutch mechanism is provided as standard to protect the motor from overload on the paddle
  • Variety of paddle shapes support detection of material with various apparent specific gravities
 

Operating Principles

Our unique switching mechanism realizes the highly stable and reliable detection regardless of the rotational direction of the paddle. When the deposit of material restricts the paddle rotated by the motor, the contact is output to stop the motor. When there is no more material to detect, the motor resumes to rotate.
