Masana’antar samar da wutar lantarki da oil & gas suna bukatar kariya mai ƙarfi ga turbines da compressors. Turbine Supervisory Instrumentation (TSI) modules na Bently Nevada suna da takardar shaidar SIL 3. Saboda bambanci da tsarin TSI na yau da kullum, wannan mafita tana ba da nazarin vibration na ainihin lokaci, sa ido mai daidaito sosai kan saurin rotor har zuwa 60,000 RPM, da bin diddigin matsayi na thrust. Wani shukar wutar lantarki mai kona kwal a Texas ya nuna ƙimarta. Tsarin ya gano karkacewar rotor na 0.02 mm awa 72 kafin yiwuwar rugujewa. Ƙungiyar ta gyara matsalar da wuri kuma ta guje wa tsayawar aiki marar shiri mai tsada.
