The EBW 20/1 is a double-idler belt scale for continuously recording of the quantity of the bulk material during the transport on a belt conveyor. Due to its compact design, the scale is particularly suitable for small belt conveyors with belt widths up to max. 1,000 mm.

The belt scale EBW 20/1 MID has a MID approval for classes 0.5; 1 and 2 according to OIML R50.

The EBW 20/1 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 with higher requirements on measuring accuracy.


Typicals fields of application: grain and animal feed, plastics, wood pellets, pit and quarry, recycling and waste management industries.


The extended frame unit of the scale allows a much higher measuring accuracy compared to single-idler belt scales.


The belt scale EBW 20/1 has a simple mechanical design. The belt scale frame is mounted on two  support bars. Within the frame, there is located the measuring rocker, which is mounted on spring steels and a load cell. The load cell is equipped with a transport and overload protection.

The low installation height allows the use for applications in conveyors with a very small interspace between the upper and lower belt.


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 20/1 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:

  • daily zeroing
  • regular checks for damage and heavy bulk deposition
  • annual adjustment with reference material or with test chain


MID approval:
In combination with a control unit that can be calibrated, the belt scale EBW 20/1 MID can be used as

  • continuous totalizing automatic weighing instrument (belt weighers) according to Guideline 2014/32/EU (MID) and OIML R50 for the accuracy classes 0.5; 1 and 2



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.
