Spee-Dee Packaging Machinery (spee-dee.com) has launched the Evolution Checkweigher, a PLC-based system that features non-proprietary controls to make it easy to calibrate and communicate with other systems in the plant.
Unlike other checkweighers that feature PC-based controls, the Evolution Checkweigher offers a communications package that provides access to data, which can then be downloaded via Ethernet IP, Modbus TCP/IP, USB and other methods. The Evolution offers end-users the ability to calibrate in the field, without the need of a Spee-Dee technician.
