The Monitor KA and KAX range of rotary paddle bin monitors consist of some of the most reliable, rugged and economical point level control sensors available for detection of dry bulk materials. These easy to install units are proven performers in a wide variety of bulk materials.

They 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.

Unlike many other available paddle units, the Monitor range of paddle level indicators incorporate a feature that automatically shuts off the motor of the unit when the paddle is in a stalled position, which both extends the life of the motor and minimizes maintenance.

The KA model is the most popular for standard applications on a wide variety of materials. The KAX version is specially designed to meet hazardous area standards.

The SafePoint fail-safe bin monitor is the state-of-the-art in rotary paddle technology. Utilising patent-pending magnetic sensing technology and a new unique housing design, the SafePoint bin monitor is the most reliable, technician friendly, rugged and economical failsafe rotary paddle point level control sensor of its kind.

The SafePoint bin monitor provides the ultimate in performance wherever critical continuous operation must be ensured. Detection of both material presence and its own operational status is performed on a continuous basis. The SafePoint level sensor monitors its electrical and mechanical operating condition. Separate outputs are provided for material sense and unit status (fault conditions).

A tilt switch provides indication by detecting the angular position of the tilt switch enclosure. Typically the unit is suspended above the material to be sensed. Internally, a steel ball centres itself over a switch resulting in switch actuation. As rising material contacts the tilt switch (or the extension actuator) the enclosure begins to tilt. When the enclosure body is tilted at 17°, the steel ball rolls off centre, deactivating the switch.

As material falls away from the switch enclosure body (or the extension actuator) and the unit becomes upright, the ball returns to its original centred position, once again causing switch actuation. The change in the internal switch status is user accessible for signalling alarms, lights, or interfacing with a PLC.

Monitor's tilt switches can be used in a variety of applications and with many different types of materials. The TC-3X can be used with materials 15-60 lb/ft³, while the TC-1 can be used with materials 45+ lb/ft³.
