Description

The EBW 20/3 VHD is a double-idler belt scale for heavy-duty applications with large belt widths. It serves to continuously record the quantity of the bulk material during the transport on a belt conveyor.

The belt scale EBW 20/3 VHD MID has a MID approval for classes 0.5; 1 and 2 according to OIML R50.

The belt scale has an extremely robust frame, which is mounted on two support bars. Within the frame, there is located the measuring rocker, which is mounted on spring steels and three high-precision,  robust shear beam load cells made of stainless steel.


This type of force transmission provides the possibility to realize a height adjustment of the measuring rocker.


The EBW 20/3 VHD is equipped as standard with an adjustment device for static adjustment check.


The mechanical construction of the belt scale ensures a very precise measuring of bulk materials in heavy-duty conveyors, e.g. in the coal and ore mining industry or in the underground salt mining industry.


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 belt scale 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 20/3 VHD MID can be used as

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

Functioning

The bulk material generates a pressure load on the measuring idler stations which is recorded by three strain gauge load cells via the special force transmission.


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 cells and the speed measurement are recorded, scaled and provided as a weight value in kg/h or t/h.
