Paddle Switch Detector
DRO
. Level detector suitable for any type of solid bulk material as well as for various applications thanks to a wide range of accessories (high temperature sleeve, paddle extension, adjustable flange, protector for horizontal mounting, …).
A special version is available for hoppers with heat insulation (DRO « CAL ») and an optional module (BTR 111) for positive security.
The paddle is driven in rotation by a gear-motor. When the level is reached, a resistive torque is detected which activates a dry contact. Power supply of the motor is cut off in order to protect it. When the level drops, the resistive torque is equal to zero and the paddle resumes its rotation.
