CONCRETE TECHNOLOGY70 CPI %u2013 Concrete Plant International %u2013 1 | 2026 www.cpi-worldwide.comPLC-based weighing unitsThe scales are controlled and monitored directly via the PLC. Weight recording, tolerance control and diagnostics are carried out centrally via the plant control, ensuring high accuracy and easy maintenance.UL certificationFor new systems or modernisation of the Motor Control Center (MCC), electrical components and control cabinets are designed and approved in accordance with UL standardsImproved system availabilityIn the event of malfunctions, error codes provide precise details, enabling rapid troubleshooting and reducing the need for manual intervention at the control cabinet.Automated moisture measurementThe updated system incorporates advanced moisture measurement for consistent mix quality. In addition, the accuracy of material dosing has been improved. This is usually within a tolerance range of 1%.Enhanced remote maintenance and diagnosticsFor instance, calibration of weighing systems can be performed remotely, allowing service technicians to analyse and adjust key parameters without an on-site visit. This streamlines support, improves operational efficiency and minimises production interruptions.New control cabinet according to UL certificationHydrotester %u2013 moisture measurement in the material flow of the aggregate siloHydromat moisture correction inside the mixer: Automatically controls the w/c ratio to ensure a uniform batch
