The online oil contamination degree moisture detector mainly can detect the particle contamination degree in oil and the moisture in the oil. The detection of the particle pollution degree in the oil liquid is to use a semiconductor laser 6 to build a photoresistance method to measure the accumulated particle number in the oil liquid on line, and can conveniently detect the size of metal particles in the oil liquid and the flow rate of the oil liquid. The traditional classical measurement method has wide adaptability.

In order to ensure that the KLD-O-S online oil contamination degree and moisture detector works normally, the hydraulic system should provide a pressure difference of not less than 20Psi (1.3Bar) for the sensors (oil inlet and oil outlet), the aim is to control the flow rate of the detected oil passing through the sensors to be between 50mL/min and 300mL/min, the recommended value is about 100mL/min, and the normal measurement result of the sensors is influenced when the flow rate exceeds the range of 50 mL-300 mL/min. And the hydraulic system should provide an absolute pressure for the sensor of no more than 10Bar, preventing damage to the moisture sensor part due to excessive pressure.
The detection oil path of the sensor is narrow, so that large particles (100 micrometers) or transparent floccules which are visible to naked eyes do not exist in oil to be detected, and the detection oil path of the sensor is prevented from being blocked. When obvious bubbles exist in the oil way, a measure for eliminating the bubbles is firstly taken to ensure that the oil liquid to be measured does not have the obvious bubbles, otherwise, the accuracy and the stability of measurement are influenced. When the sensor pipeline is cleaned, an isopropanol solution is selected for cleaning, a petroleum ether solution is not used for cleaning the sensor oil way, otherwise, the water sensor part can be corroded, and the water sensor is damaged.
