The Relco Delta 4 real-time weld quality analyser represents the next step in induction sealing technology. Designed for industries where precision, consistency, and reliability are essential, the Delta 4 provides real-time monitoring of every seal, ensuring optimal performance and preventing maintenance issues before they occur.
Since its launch, this real-time weld quality analyser has been adopted by clients worldwide across sectors such as food and beverage, pharmaceuticals, cosmetics, and chemical manufacturing. It’s helping production lines achieve new standards of quality control, efficiency, and uptime.
How the Delta 4 Real-Time Weld Quality Analyser Works
The Delta 4 is installed between the induction generator and the sealing head, with virtually zero insertion loss. This means it does not interfere with the sealing process — instead, it adds an intelligent layer of analysis through advanced real-time weld monitoring.
During every sealing cycle, the real-time weld quality analyser captures key performance data, including:
⚡ Voltage (V RMS) – crucial for weld strength
🔋 Current (mA RMS) – indicates system performance
⚡ Energy (Joules) – measures the energy delivered per seal
⏱ Time (ms) – defines sealing duration and consistency
🌐 Frequency (Hz) – monitors system stability
This information is sent to the PLC where users can input target values and tolerance ranges. The Delta 4 enables automatic discrimination between acceptable and unacceptable seals, ensuring every product meets the required quality standard.
Predictive Maintenance with a Real-Time Weld Quality Analyser
Beyond quality assurance, the Delta 4 real-time weld quality analyser is also a powerful tool for maintenance prevention. By continuously monitoring trends in voltage, current, and frequency, it helps operators identify anomalies and potential system issues early — reducing unplanned downtime and maintenance costs.
This predictive approach to equipment health improves reliability while supporting a data-driven maintenance strategy, giving manufacturers more control over their operations.
