Junction boxes for load cells

When building a scale, summing boxes or cable boxes are an essential component. These can be used as junction boxes for parallel connection of load cells or as cable boxes for extending load cell cables. There are variants for connecting 4 (industrial scales), 6 or 8 load cells (large weighing bridges, vehicle scales). Depending on the design, load cells can be connected using 4 or 6-wire technology. Our summing boxes offer a wide range of possible areas of application.

Junction boxes for load cells for every application

Depending on requirements, up to 8 load cells can be connected and interconnected. The housing material can be chosen between ABS or stainless steel AISI 304 and thanks to the protection class IP67 certification, the boxes can also be used in harsh environments without worry. If you have any questions, our technical sales staff will be happy to advise you so that you can make the right choice for your measurement needs.

Digital junction boxes / terminal boxes

- have an integrated converter for load cells 0-10V and load cells 4-20mA.

If an A/D converter is integrated in the cable box, it is called a digital cable box. This outputs a digital weight value after conversion. The load cell signal is only amplified by an analog amplifier installed in the cable box and output as an analogoutput signal (0-10V or 4-20 mA)issued.

When calibrating a scale, corner load errors may be detected. These can be electrically adjusted in the cable box. A so-called corner load adjustment is carried out. Depending on the model, this corner adjustment is carried out in different ways:

  • via an integrated resistance network in the load cell output
  • with fixed resistors for each individual load cell separately
  • with soldered fixed resistors
  • with potentiometers already soldered on.

The terminal or cable boxes from octogon, which have already proven themselves in daily use in industrial and vehicle scales, have a solid housing (optionally stainless steel, plastic or die-cast aluminum housing) and are of high quality. Depending on the design, the screw connections can be made of plastic, stainless steel or nickel-plated brass. To ensure better protection against possible moisture ingress, the cable boxes should primarily be mounted so that the cable ducts face downwards.

Load cell 0-10V & load cell 4-20mA

The signals can be evaluated directly via the load cell junction box. For this purpose, a digital junction box for load cells is required, which enables the signal to be output in the two analog values ​​0-10V & 4-20mA.
