The EBW 20/2 is a multiple-idler belt scale for two or three measuring idler stations. The scale serves to continuously record the quantity of bulk material during the transport on a belt conveyor.
The belt scale EBW 20/2 MID has a MID approval for classes 0.5; 1 and 2 according to OIML R50.
The EBW 20/2 is a built-in belt scale for stationary belt conveyors, also for legal-for-trade applications. It is used for exact weighing and dosing of bulk materials such as chalk, gravel, fuel surrogates, wood pellets, grain, animal feed and plastics.
The belt scale EBW 20/2 is often used in the pit and quarry industry, in the glass and metal industry, in the recycling industry and in waste management.
The longer weighing section of double-idler belt scale leads to a longer retention time of the bulk material on the scale and thus a much higher measuring accuracy compared to single-idler belt scales is ensured.
The EBW 20/2 can be used in almost every conveyor. The low installation height allows the use for applications in conveyors with a very small interspace between the upper and lower belt.
The belt scale has a simple mechanical design. The frame is mounted on two support bars. Within the frame, there is located the measuring rocker, which is mounted on spring steels and two high-precision load cells. Each load cell is equipped with transport and overload protection.
As standard, the belt scale is made of angle steel profile and painted, optionally powder-coated, hot-dip galvanised or made of stainless steel.
Easy installation:
The EBW 20/2 can be installed easily. Weighing frame and measuring rocker are delivered fully assembled. The scales’ support bars are easily screwed upon the conveyer. The existing idler stations are mounted on the measuring rocker as measuring idler stations that there is no force shunt to the frame of the belt conveyor. By exchanging the support bars, the scale can quickly be adjusted to another belt width.
Low maintenance:
The robust construction of the belt scale requires low maintenance. It works reliably for years, as long as no external disturbance occurs (lightning strike, overload, etc.).
We recommend to comply with the measuring accuracy:
MID approval:
In combination with a control unit that can be calibrated, the belt scale EBW 20/2 MID can be used as
The bulk material generates a pressure load on the measuring idler stations which is recorded by strain gauge load cell.
At the same time, the measuring wheel running simultaneously on the lower belt and records the current belt speed.
By the control unit, the signals of the load cell and the speed measurement are recorded, scaled and provided as a weight value in kg/h or t/h.
