The Technological Development Centre for Remote Acquisition and Data Processing Systems (SARTI UPC) worked with the Department of Maintenance, Inspections and Testing of the Ascó nuclear power station to develop a system for calibrating vibration sensors. The PC-based system that works via an application developed in LabVIEW automatically calibrates these sensors against ISO 16063-21 and ANSI S2.11 standards.

The calibrations enable the correct operation of the sensors to be calibrated in the nuclear power station’s calibration laboratories, to confirm whether the measurement error is within the margins defined by the manufacturer or for a specific measurement task in the power station.

The research led to the development of a driver to control OROS acoustic and vibration analysers in the LabVIEW programming environment, the instrumentation that was used in the project to generate the vibration signal and acquire the sensor measurement to be calibrated.
