Description
AECO VIBRATION LEVEL CONTROLS:
When it is important to determine if solid powder or granular particles are at their minimum or maximum depths, AECO vibration level controls are used. They are used for level control in silos for the storage of animal feed, flour, sawdust, sand, cement, and other bulk materials with a density greater than 30 g/litre and a maximum particle size of 8 mm. And in foundries and cement manufacturing facilities. Controllers based on this technology are safe to use around food.
They work by actuating a vibrating fork with two rods that are actuated by an electric source.
When the vibrating fork makes contact with the material to be controlled, the oscillation is damped, the vibration decrease is electrically sensed, and a switching signal is created.These gadgets are extremely durable and come in an aluminum housing with AISI 316 stainless steel connectors. They withstand large mechanical stresses because to the restricted extent of the vibrating fork, are easy to operate, and require little maintenance.
