A Tratec sampler consists of the following main components. A housing, a cup, wheels and a pneumatic cylinder (see picture below).

The sampler can be implemented directly in the conveyor system, under material in free fall between two conveyors (see example in the picture below). The pneumatic cylinder moves the cup along the grooves in the sampler. During this movement, the cup extends through the flow of material, collecting material in the cup. When the cup is full of material, the pneumatic cylinder retracts and moves the cup back to the starting position.

The sampler can be operated manually or connected to a PLC programme. There are sensors located in the pneumatic cylinder to register the opening and closing position. The time sequence for filling material is controlled by a pneumatic timer or by a PLC programme.
