JBA

The model JBA Load Cell Active Junction Box is an active summing junction circuit that accepts inputs from any strain gauge based sensor (load cell, force sensors, pressure sensor, torque sensor) and applies individual gain adjustment before combining them to provide a trimmed and summed output. For a simple summing circuit with no trimming and no corner compensation, use the Load Cell Junction PCB, model JPP Load Cell Junction PCB, and for fault monitoring and fault detection alarm features, use the Load Cell Junction Box with Fault Monitoring, model LCI Load Cell Junction Box with Fault Monitor.

• Sums the outputs from up to 4 x 350~1000 Ohm strain gauge load cells
• Individual gain adjustment provided for each channel
• No interaction between offset and gain
• No interaction between channels during calibration
• Simplifies installation of multi-cell platforms, silos, tanks and hopper weighing systems
• Wide input range - from 0.5 to 20 mV/V

For a simple summing pcb with no trimming capability:

• see model JPP

 

For summing, fault monitoring and fault alarm capability:
