New device improves concrete quality monitoring

REO has launched the SWM4000, a new handheld vibration monitor designed to help improve the quality of precast concrete. The device measures key vibration data during concrete compaction, helping manufacturers reduce defects and meet industry standards.

Concrete quality depends heavily on proper compaction to remove air pockets and create a dense, uniform product. Vibration tables, which use electromagnets like the REO Type WI21, are commonly used to achieve this. The SWM4000 allows operators to measure and adjust the vibration process more accurately.

Steve Hughes, managing director of REO UK, explained the improvements over the previous model, the SWM3000. "We learnt quite quickly that the SWM4000 needed to be much tougher than the old version," he said. "We expected most units to be used in clean labs, but the reality couldn’t be further from the truth. The new unit is much more rugged, with a rubberised case, higher environmental protection, and a more robust user interface. The battery life is also much longer."

The SWM4000 measures frequency (Hz), oscillation amplitude (mm), oscillation speed (cm/s), and oscillation acceleration (g). It connects to an accelerometer that can be clamped or magnetically attached to a vibrating table. Data can be stored and exported to a PC for further analysis.

The SWM4000 is designed for quick use on-site in any weather. It runs on rechargeable batteries and doesn’t require additional software or mobile devices.

With the growing demand for precast concrete due to its efficiency and sustainability, ensuring consistent quality is more important than ever. The SWM4000 helps manufacturers meet standards like BS EN123890-2:2019 and ASTM C192, while also supporting internal quality control processes.
