Junction Box

Junction Box JB-2/JB-4

This junction box is used to connect two or four strain gauge type transducers and average the outputs of those transducers. The mean value is easily measured by a digital indicator or data logger. 
It can also be used as a branching box to divide the connection of switching boxes into two or four series.

• Example of use as an input averaging junction box
  • Strain gauge type transducers to be connected must be of the same capacity, rated output and input/output resistance
  • The input/output resistance viewed from the instrument is as follows.
       (Input/output resistance of one transducer) divided by (Number of connected transducers).
       The calculated value above must be within the range of the instrument specification.

  Example of use as a branching box

  As the inside of the junction box is wired with 7 wires (for terminals A to G), the junction box can also be used as a branching box as the above. Each connection between the data logger, junction box and switching boxes must be made using an exclusive 7-core cable specified by us.
