Oil Condition Monitoring Sensors PPM-HLF-2
The PPM-HLF-2 oil condition monitoring sensor is an intelligent online oil analysis sensor for online measurement of oil quality changes. Its unique measurement technology is extremely sensitive to changes in oil quality. It can continuously monitor oil quality indicators on-line in real time and provide 360° All-round real-time online monitoring provides a reliable and powerful guarantee for the continuous and reliable operation of valuable equipment.
Measuring principle Polarization Field Strength Distribution of Liquid Between Capacitor Plates
According to the characteristics that the dielectric constant of the oil changes with the change of its moisture content, wear particles and acid value, the capacitance sensor is used to monitor the change of its dielectric constant in real time, so as to analyze the moisture content in the oil, the wear particles and the acid value. value changes. The significant advantage of the dielectric constant monitoring subsystem is that it can monitor the comprehensive performance of the oil, and grasp the aging and pollution of the oil as a whole
