Single-point load cells for filling applications
Mettler Toledo’s single-point SLP85xD load cells are designed to be built into large networks to enhance productivity when multiple bottles, cans or drums are weighed within a fraction of a second simultaneously and in parallel. Fully integrated electronics can capture 1,200 weight values per second, making them ideal for multi-line filling and checkweighing applications. Quick connectivity via EtherNet/IP, Profinet IO RT or Profibus DP is incorporated into the compact unit for easy integration and start up. It also minimizes efforts for wiring and requires less material, which saves costs for the machine manufacturer. The protection safeguards the module from outside forces regardless of direction of origin, protecting the accuracy of the module both during normal operation and equipment malfunction events.
The load cell can be used either to control the entire filling process with its digital outputs or as a sensor only to provide fast weight results to the control system. In both cases, a fast update rate of the weight values ensures the fastest reaction times for controlling the filling valves. The load cell also transmits diagnostic information to the control system about its own health status and about the status of the filling application. This information can be used for predictive maintenance to minimize downtime.
