Advantages of valve dynamic loss sensor
PSA vibration special produced by our company is a local transmitter for on-line real-time monitoring of bearing vibration of rotating machinery, also known as integrated vibration sensor. It is a kind of absolute vibration measurement of the machine. It can be installed on the bearing pedestal or casing of the machine to monitor the machine in real time. At the same time, the two-wire system outputs 4-20 mA current signal, which can be directly supplied to the PLC or DCS monitor, collector, recorder or other monitoring equipment in the control room. In case of machine failure caused by bearing wear, bearing cracking, poor dynamic balance and misalignment, the integrated vibration transmitter can detect the fault in advance and give an alarm, so as to prevent the PSA equipment from damage caused by continuous operation under poor conditions, thus bringing economic losses.
