Feature
The mechanical consumables in the motor have been omitted thanks to our proprietary mechanism, which has realized the long life duration and stability that were impossible for the conventional rotary type level switches!
Its performance is outstanding in processes that includes frequent ON/OFF operations.
- High-temperature specifications and load bearing specifications are available.
- As the internal mechanism has been unitized, the switch can be replaced without detaching the main body from the tank.
- A clutch mechanism is provided as standard equipment to protect the motor from overloads on the paddle.
- Various apparent specific gravities can be supported by selecting a suitable paddle shape.
Operating Principles
Our proprietary switching mechanism realizes the highly stable and reliable detection regardless of the rotation direction of the paddle. 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.
