Precise and Reliabile Level Indicators for Powdery and Granular Materials
ITL Rotating Level indicators are designed for level monitoring of bins, hoppers or silos by means of the rotating paddle. When the materal level reaches the measuring paddle the rotation is blocked. The motor is freely suspended within the casing. The resulting reaction torque activates a limit switch output single that stops the motor. As soon as the material level sinks below the paddle radius, a spring pulls the motor back into its operating position. The switch returns to the OFF position and the motor is switched on. The top or side-mounted indicators are commonly used for materials having a minimum bulk density of 0.3 t.m3 (0.01 lbs per cu in).
