SL-RC3D Column Digital Load Cell
The digital SL-RC3D compression load cell features embedded electronics that improve system accuracy and load cell handling and allows the user to communicate with each load cell independently. It’s designed so that multiple cells can be wired together in a daisy chain to the indicator, greatly simplifying installations by avoiding the need for a junction box.
Product description
The digital SL-RC3D compression load cell features embedded electronics that improve system accuracy and load cell handling and allows the user to communicate with each load cell independently. It’s designed so that multiple cells can be wired together in a daisy chain to the indicator, greatly simplifying installations by avoiding the need for a junction box.
The SL-RC3D is compact and robust, built from high-grade stainless steel and fully hermetically sealed; its performance can be relied upon in even the harshest of conditions. A rocker column design helps ensure optimum weighing accuracy when subjected to off-centre forces from scale deck movements.
The SL-RC3D can be provided with either the standard connectors or cabled connectors. The cabled variant is detailed at the end of this datasheet.
Applications
Weighbridges, hoppers, tanks and silos.
Accessories + Options
Standard connectors or cabled connectors available
