The BINMASTER® BMRX Rotary Level Indicator is a significantly advanced rotary level indicator that exceeds the performance of competitive rotaries. The BMRX is designed to provide security from system power failure, easy access to all components, and reliability for a long life. An explosion-proof housing is standard on all BMRX Rotaries. The BMRX is cost-effective and the easiest-to-implement solution for reliable point level control.

The BMRX Rotary Level Indicator is built with a specially designed synchronous motor that features "de-energized" operation. The motor automatically shuts down when material is present rather than remaining in a "stalled" condition. This reduces "wear and tear" and the operating temperature which extends motor life. Plus, the motor features a built-in bi-directional slip clutch that protects the gear assembly from damage due to over-rotation. Also standard is a four-bearing drive shaft assembly that reduces motor drag during paddle rotation.

Principle of Operation

High Level Control During Filling
As a high level control, the paddle rotates continually when material is not present. When material reaches the paddle, the resistance causes the motor to rotate an actuator arm over to a limit switch that is wired to some type of alarm or process equipment.

Low Level Control When Emptying
As a low level control, the paddle is stopped and the motor is "de-energized" when material is present. When material drops below the paddle, an actuator arm springs back into place, causing the motor to "re-energize" and the paddle starts rotating. This will send an alert to an alarm automatically start up a process system.
