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.
