It seems too good to be true, a system that can find out if independent load cells are functional or not. Even better,- a system that can automatically adjusting the calibration when a load cell or the weighing indicator has been changed!
Most measuring and weighing systems, based on strain gage load cells, consist of more than one sensor. These sensors are usually connected analogue by a junction box. Since the sensors are all connected parallel, the average measurement of the sensors is sent to the system. This way of operation works fine, until a load cell breaks down. The challenge usually is to find out which of the loadcells is defect. This is usually not sufficiently identified and the system continues to operate with a deficiency.
In order to overcome this drawback we developed an ”intelligent” load cell cable junction box, the SIGMA4. During a system test, the junction box and the indicator measures the load cell output per sensor, compares this against
