Duplex Debris Monitor
Detection of Lube System Gear and Bearing Failures for High-Value
Power Generation or Non-Interruptible Production
Duplex debris monitor is an on-line, full flow debris sensor and
housing for lubrication systems, that captures, retains and
remotely indicates magnetic wear debris, generated by surface
fatigue failures of oil-wetted, components, in real-time.
The sensor-retained debris can be removed and
analyzed for further information about the nature and site of the
impending failure, in many cases, without the need to shut down
the equipment being monitored!
On-line, early warning of potential failures can be provided
well in advance of actual loss of function, permitting repairs to
be performed during scheduled shutdowns, with little or no loss of
precious, expensive, operating time.
The Duplex monitor consists of a scavenge or return line-mounted,
dual chamber housing, with a rated flow up to 30 gpm of
lubricating oil. The chambers, each with its own debris sensor,
are mounted in an alternate-flow arrangement. Typically, only one
chamber is used to monitor the total flow from the system. If the
powerful magnetic sensor captures gear or bearing debris, a remote
signal alerts the operator to switch the flow to the alternate
chamber. The first chamber, now isolated from the oil, may be
depressurized and opened to retrieve the debris particles for
inspection and analysis, without the need to shut down the host
system is suitable for high-value stationary or mobile equipment,
where cessation of operation for unscheduled maintenance cannot be
tolerated. For further information, contact Tedeco's sales
department with your application.
