Test and Replace Hydraulic Hoses Only as They Break Down

Eaton's LifeSense system enables operators to monitor pressure hoses in real-time and replace as necessary.

'Nothing quite so messy, and potentially dangerous, as hot hydraulic fluid spraying from a ruptured hose under load!

Now, that scene can be largely avoided with timely monitoring of system hoses and replacing those that test positive for imminent breakdown. It's all possible through Eaton Corporation's new LifeSense hose and monitoring equipment -- designed to give warning of hose failure ahead of the red mess.

Working with Purdue University, Eaton developed LifeSense to improve equipment efficiency and protect those who work around hydraulics.

Rather than using an arithmetic calculation as to when a  hose may fail, LifeSense actually detects when a hose if nearing the end of its useful life. Then, an alert is sent to the user so the assembly can be replaced to prevent down time or injury. A single LifeSense monitoring unit can handle input from multiple hose locations.

Eaton Product manager Doug Jahnke says most operations replace all hoses on a pre-determined schedule to avoid problems, but that can be very expensive, particularly if only a few hoses in the system are suspect. Using the LifeSense system, he says users can usually get considerably more life out of an individual hose -- up to 50% more than in a typical lab test -- by monitoring its condition and replacing it only when necessary.
