Sipel offers a complete line of junction boxes (or adder boxes) for both normal and adverse environmental conditions.
In plastic and cast aluminum versions, for 4 or 6 cells, with and without protection for atmospheric discharges, for digital or analog cells, we cover a wide range of use and applications.

Characteristics:
The analog junction boxes have equalization adjustments for each of the cells. The connection output to them is in 5 wires (+Excitation, -Excitation, +Signal, -Signal and GND). 
The analogue and digital junction boxes with 6 cubicles have protection against atmospheric discharges, an input terminal block and an additional output terminal block for connection to a second junction box.
The junction boxes with protections can have from 2 to 6 cells, giving an important versatility in adverse weather conditions.

Applications:

Small and large capacity platforms
Weighing hoppers
Automatic machines (bagging machines, dispensers, continuous weighing systems, etc.)
Special high capacity scales 
Tanks
Analog and digital truck scales
Axle Scales
And any special application that requires its use.
