Monitor Technologies' Model KA / KAX line of rotary paddle bin level indicators consist of the most reliable, rugged and economical point level control sensors available for detection of dry bulk materials. These easy to install sensors are proven performers in a wide variety of bulk materials. Monitor's paddle switches can be used to eliminate bin overflow, maintain a predetermined material level, indicate plugging of conveyors and pneumatic lines or provide any of a number of level control functions. Monitor's paddle level indicators incorporate a feature that automatically shuts off the motor of the unit when the paddle is impeded by material, which both extends the life of the motor and minimizes maintenance. The Model KAX incorporates all the features of the Model KA, but is specially designed to meet hazardous location standards.
