  • Lubricant monitoring system
    Patent number: 4505186
    Abstract: The lubricant monitoring system comprises an element which absorbs a liquid lubricant on the piston rod between a lubricant wiper assembly surrounding the same and a seal which surrounds the piston rod where the rod enters the compressor cylinder and an electrode of a measuring capacitor (CM) near the element. The lubricant absorbent element acts as the dielectric of the measuring capacitor.In the event of a fault on the lubricant wiper assembly, liquid lubricant is absorbed by the absorbent element so that the dielectric constant changes. This can be utilized for an alarm.
