Abstract
A control system for a centrifuge is disclosed, that comprises: a controller that receives a first pressure signal indicative of a first pressure of a product flowing into or out of the centrifuge, and a second pressure signal indicative of a second pressure of an operating fluid flowing into or out of the centrifuge. The controller is configured to: determine a first pressure difference between the first pressure and the second pressure; an in response to the first pressure difference dropping below a first predetermined offset, output a first control signal that causes a back pressure of the product flowing out of the centrifuge to increase.

A control system for a centrifuge, comprising:
- a controller that receives a first pressure signal indicative of a first pressure of a product flowing into or out of the centrifuge, and a second pressure signal indicative of a second pressure of an operating fluid flowing into or out of the centrifuge, the controller being configured to:
- determine a first pressure difference between the first pressure and the second pressure;
- and
- in response to the first pressure difference dropping below a first predetermined offset, output a first control signal that causes a backpressure of the product flowing out of the centrifuge to increase.
A method of controlling a centrifuge, comprising:
- receiving a first pressure signal indicative of a first pressure of a product flowing into or out of the centrifuge;
- receiving a second pressure signal indicative of a second pressure of an operating fluid flowing into or out of the centrifuge;
- determining a first pressure difference between the first pressure and the second pressure;
- and
- in response to the first pressure difference dropping below a first predetermined offset, increasing a backpressure of the product flowing out of the centrifuge.
