Measuring the level of bulk better in may ways
For more than 65 years, Maihak’s rotating paddle level indicators have proven to be rugged, safe and reliable. Now, Maihak has developed a new rotating paddle indicator: the MaihakMBA 200. The valued rugged construction has been improved with many attractive and functional advantages.
With the choice of MaihakMBA 200, time and costs can be optimised. The standardised components can be selected to offer differentiated solutions for the individual applications. The variations are clearly and distinctly structured in order to prevent mistakes when selecting the proper model. Also, important are the many precise details which make the MaihakMBA 200 a reliable and durable level indicator.
The MaihakMBA 200 switches as a full, demand or empty indicator of bulk products in large storage silos as well as in small containers. In drop tubes and conveyor systems, the indicator provides a quick signal to indicate a blockage in product flow. Even under difficult installation conditions, it functions reliably.
Overview
A synchronous motor slowly rotates the paddle wheel. When the bulk material reaches the paddle, the rotating motion is blocked. The counter torque is used to turn the motor mechanism against a switch which in turn shuts off the motor. This condition is electronically transmitted via a relay switch contact. As soon as the bulk material frees the rotating paddle, the motor mechanism is returned to it’s operational position by means of a spring. The switch is released and the paddle begins to rotate again.
Typical Applications
- As full, demand or empty indicator in silos or storage containers
- As a blockage indicator in drop tubes
- As a full indicator during filling operations
