Product Details

The Strain Gauge Summing Junction Box JBA is an active summing junction box for up to four load cells.  It actively sums the outputs from up to 4 x 350 -1,000 O hm strain gauge load cells.

The JBA can accepts inputs from any strain gauge based sensor for example load cell, force sensors, pressure sensor, torque sensor.  The strain gauge summing junction box provides a calibrated and summed output by applying individual gain adjustment to the strain gauge inputs before combining them to provide a calibrated and summed output.
