Speed Sensors & Zero Speed Switches | Features & Benefits

Speed sensors detect speed changes in rotating equipment such as screw conveyors, bucket elevators or belt conveyors. Zero speed switches are very similar to speed sensors but detect the lack of speed or zero speed in rotating equipment. Speed sensors and zero speed switches are used to protect equipment and processes.

Screw Conveyor - an overview | ScienceDirect Topics

An auger conveyor (or screw conveyor) consists of a helicoid screw rotating within an enclosed tube or open U-tube (Fig. 3.7).Its invention is credited to Archimedes (287-212 BC) who used it to pump water from the holds of ships (CEMA, 2003).With only one moving part in contact with grain, low-cost augers are simple and find extensive use especially in intermittent use conveying systems.
