Means for fault diagnostic system setup for NGV-refuelling stations compressor equipment

In the article we research the means for fault detection system set up for NGV-refuelling stations compressor equipment. It is a real-time diagnostics while operation. Equipment technical state is estimated in accordance with vibration index analysis. The fault detection system helps to vary frequency till fifteen harmonic components of generated signal and vibration acceleration and gives opportunity to input frequency deviation input at preset range artificially. Here are two ways of measuring channel scheme.
