Features

 
  • Special model withstandable against high temperature and heavy load
  • As the internal mechanism has been unitized, the switch 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
