Vibration Tests on Nine Different Flowmeters

Kurzfassung

Vibration tests in accordance with DIN EN 60068-2-6 and IEC 68-2-6 were performed on nine flowmeters. The flowmeters were manufactured by ABB Automation GmbH Göttingen and are of different types and with different nominal diameters. The flowmeters were mounted on a multi-axial test facility and sine sweep runs into the direction of the three translational axes were performed. The frequency range of the sine sweep runs was 10 to 100 Hz with a maximum acceleration level of 3 g. In each axis the flowmeters were exposed 66 min to the vibrations. The visual inspection of the flowmeters after each test run showed no visible damage. After termination of the test programme, the flowmeters were transported to ABB and inspected in detail. Also, the calibration was checked by ABB.
