Watchdog keeps check on hydraulic fluid
quality
A novel and highly accurate method of fluid health monitoring opens up new possibilities for continuous "online" monitoring of hydraulic systems.
With over 50 years of servo valve manufacture behind them, the engineers at Moog reckon they have a better appreciation than anyone of how fluid contamination can lead to the failure of hydraulic systems This knowledge has enabled them to develop an innovative product that uses the failure mechanism itself to provide a warning of system cleanliness problems

EPDM seals provide compatibility with Skydrol to type V, LD4, 500B4 and Hyjet, the standard hydraulic fluids used in aviation manufacture.
Research has shown that particle counting is relatively easy when there is a large population of particles over 10um.
Below this size, existing technologies exhibit weaknesses.
Moog has conducted extensive testing and trials that show a "gravimetric" approach to be more consistent and discerning at the sub-10um level.
As a result the company has worked to develop this phenomena into a new and highly accurate method of fluid health monitoring which opens up new possibilities for continuous "online" monitoring of hydraulic systems.
"Over 80% of component failure in hydraulic systems are the direct result of fluid contamination", says Mike Baker, Engineering Manager at Moog Controls.
"And more often than not, the user wrongly blames the component".
Moog therefore believes that it is essential to help its customers protect their systems against such failures.
"For many years we have been preaching the need for fluid cleanliness to our customers", says Baker, "but now we are offering an instrument that will monitor the system 24/7".
The new product, called the Watchdog-Monitor, is aimed at those operators who do not want to live with the consequences of unplanned system downtime.
They demand an instrument that is easy for maintenance staff to use, but is also sensitive enough to flag up changes that may cause system failure.
Features of the Watchdog-Monitor include: tough robust construction designed to withstand harsh industrial and climatic condition; simple traffic-light data presentation; consistent measurements irrespective of environmental or system variations; no need for skilled staff to operate; not affected by aerated or opaque fluids; and the ability to track fluid contamination levels on an on-going basis in "real time".
