System detects when hydraulic hose nears end of its useful life

24 March 2011

Eaton Corporation has introduced new technology that enables reporting of imminent hose assembly failure by means of real-time monitoring of high pressure hydraulic hose assemblies. LifeSense hose, essentially a hose condition monitoring system, was introduced to the North American market at the International Fluid Power Exposition in Las Vegas earlier this week, and will launch in Europe at Hannover Messe 2011 early in April.

LifeSense hose was developed in conjunction with Purdue University and the Purdue Research Foundation's Office of Technology Commercialization to continuously monitor the health of hydraulic hose assemblies and alert users when an assembly approaches the end of its useful life. The system can monitor and track the health of each hose assembly, and neither estimates nor predicts via algorithms when a hose is going to fail. Instead, LifSense actually detects when a hose is nearing the end of its useful life and sends an alert to the user for timely replacement. A single monitoring unit can handle input from multiple hose assemblies.

The initial LifeSense hose offering will include widely used -8, -12 and -16 two-wire hose assemblies. It offers performance equal to industry standard 2SN pressure-rated hose and is certified to the same industry specifications as conventional hydraulic hose products. The technology is currently available for trial with factory-made assemblies including straight JIC swivel fittings.
