PAJ has from specifications from MAN Diesel & Turbo Copenhagen developed and manufactured a sensor for marine user, that measures water content in lubrication oil. The water-in-oil sensor can be used to measure the water activity in the lubrication oil of a marine engine and other applications, where it is crucial to measure the water content in oil.
It is important to keep the quality of lubricating oil, on large 2-stroke engines at a constant high level. An essential part of this monitoring is to ensure that the water activity does not exceed specified limits.
Water in lubricating oil can come from various sources, such as leaking coolers, or leaking parts within the coolant system.
Problems arising in connection with water in lubricating oil are corrosion of engine parts, reducing the oil's ability to withstand pressure, water emulsification, leaching of oil additives, etc,.
The traditional standard procedure for monitoring is carried out by taking an oil sample and analyzing it, either aboard ship or by sending it to laboratories ashore.
This approach has some drawbacks:
The small oil sample volume constitutes a problem. It may not represent the many tons of oil.
Some time will elapse before the result returns from the lab.
The analysis is typically only conducted one per week or twice a month.
If the test is conducted aboard it’s highly dependent on the crew personnel.
When the result return, the damage might actually have taken place already, due to high level of water in the oil.
These drawbacks can be eliminated by installing PAJ WIO200 Water-In-Oil sensor in the lubricant oil system.
Performs measuring on the entire oil volume
Online measuring – 24-7
The measurements are independent of the crew on board
Early alarm at unacceptable amount of water
Can be connected directly to the ships existing monitoring system
When water in the lubricating oil is detected early, the crew may intervene before damage occurs to the machinery and expensive accidents can be prevented.
