Product Overview


Rotary Paddle Type Level Sensor Switch NM-SC

This standard rotary type level switch supports every condition. As it can be handled easily, it is operated stably for a long term.

  • As the internal mechanism has been unitized, the switch can be replaced without detaching the main body from the tank.
  • Various apparent specific gravities can be supported by selecting a suitable paddle shape.
  • A clutch mechanism is provided as standard equipment to protect the motor from overloads on the paddle.
Operating Principles
When the deposits of measured substances restrain the paddle being rotated by the motor, the contact is output to stop the motor. When there is no more deposit left, the motor resumes rotation.
