PRODUCT OVERVIEW

Belt Sway Switch is a protective switch for detecting the meandering (sway or deviation) of belt conveyors, and sends out an alarm signal and an emergency stop signal.

It’s suited to be used for belt breakage prevention and orefalling prevention due to the belt sway. Widely used in iron and steel, cement and chemical plants, thermal power plants, etc., since it is essential for safety operation of belt conveyors.

The BELT SWAY SWITCH functions in two ways：Detecting any deviation or sway in the conveyor belt and providing an alarm and sending out signal to stop the conveyor.

Use of this switch in material transport system can prevent damage to the conveyor belt and/or drive system and avoid consequential confusion on transport lines in the event of an accident.

FEATURES
