MECHANICAL  RESTRAINTS  (pipes,  etc.)

:  When  pipes  are  present,  we  recommend  the  use  of 

hoses and flexible couplings with open mouthpieces with rubber protection; in case of hard pipes, 

place the pipe support or anchor bracket as far as possible from the weighed structure (at a distance 
at least 40 times the diameter of the pipe). 

WELDING

: Avoid welding with the load cells already installed. If this cannot be avoided, place the 

welder ground clamp close to the required welding point to prevent sending current through the load 

cell body. 

 

WINDY  CONDITIONS  -  KNOCKS  -  VIBRATIONS

:  The  use  of  weigh  modules  is  strongly 

recommended for all load cells to compensate for misalignment of the support surfaces. The system 

designer  must  ensure  that  the  plant  is  protected  against  lateral  shifting  and  tipping  relating  to: 

shocks and vibration; windy conditions; seismic conditions in the installation setting; stability of the 

support structure. 

 

EARTHING THE WEIGHED STRUCTURE

: By means of a copper wire with suitable cross-section, 

connect the cell upper support plate with the lower support plate, then connect all the lower plates to 

a single earthing system. Electrostatic charges accumulated because of the product rubbing against 

the pipes and the weighed container walls are discharged to the ground without going through or 

damaging  the  load  cells.  Failure  to  implement  a  proper  earthing  system  might  not  affect  the 

operation of the weighing system; this, however, does not rule out the possibility that the cells and 

connected instrument may become damaged in the future. It is forbidden to ensure earthing system 

continuity by using metal parts contained in the weighed structure. 

 

FAILURE TO FOLLOW THE INSTALLATION RECOMMENDATIONS WILL BE CONSIDERED 

A MISUSE OF THE EQUIPMENT
