Calibration capacity of sensors doubled on MetroBath-based RPI (www.rpiuk.com), a leading specialist manufacturer of precision positioning devices for high-accuracy rotary and angular inspection systems, has supplied a LabStandard rotary table to Worldsensing, enabling the Internet of Things technology provider to double the calibration capacity of its wireless tilt-meter (used in the construction of a new tunnel for the Grand Paris Metro).

Worldsensing installed its data acquisition system in the tunnel, with data nodes connected to sensors every 100m to enable early detection of structural instability during the construction process.

RPI’s LabStandard was used to calibrate 16 sensors at a time — doubling the initial calibration capacity, while also saving a significant amount of time and money, as well as enhancing workforce safety.

Juan Perez, wireless monitoring expert at Worldsensing, said: “Thanks to RPI’s LabStandard, we could be confident that our wireless tilt-meters were calibrated accurately.

“This in turn meant that the construction company could rely on accurate data to monitor any movement during the build.”

Dave Smith, RPI sales engineer, said: “With its ability to verify performance via calibrations traceable to international standards, we were confident that LabStandard was the ideal solution for Worldsensing’s wireless operating system, which relied on sensors to monitor tilt response and motion with extreme accuracy along the Grand Paris Metro tunnel.”
