Oil Condition Sensor and Display for Hydraulic Systems

The LPC-Z Online Oil Contamination & Water Content Detector focuses on detecting particulate contamination levels and water content in oils. For particulate contamination detection, it uses a semiconductor laser and operates on the classic light obscuration principle to measure particle diameter (µm) and particle size distribution in real-time. For water content (trace moisture) detection, it employs a moisture sensor to measure two physical quantities in real-time: water activity and temperature in the oil.

The LPC-Z utilizes an advanced, patented full-spectrum method.By analyzing the differences in optical characteristics between bubbles and particles, it accurately identifies and eliminates bubble interference, thereby precisely calculating the actual particle count in the oil, providing users with more reliable oil contamination data.
