Eaton Announces Breakthrough
in Hydraulic Hose Technology – The Hose That Knows

Eaton Corporation recently announced the launch of a new breakthrough technology that enables reporting of imminent hose assembly failure by means of real-time monitoring of high pressure hose assemblies used in hydraulic systems. Eaton’s LifeSense™ hose, a patented hydraulic hose condition monitoring system, were introduced to the North American market at the International Fluid Power Exposition held in conjunction with CONEXPO-CON/AGG in Las Vegas, March 22-26, and to the European market at Hannover Messe 2011 in Hannover, Germany, April 4-8.

Eaton’s 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 LifeSense hose can monitor and track the health of each hose assembly in a hydraulic system. This system does not estimate or predict through arithmetic calculations when a hose is going to fail, like some products on the market today. The LifeSense hose actually detects when a hose is nearing the end of its useful life. Then an alert is sent to the user so that the assembly can be replaced to prevent downtime. A single monitoring unit can handle input from multiple hose assemblies.

“Most hydraulic maintenance programs are designed to avoid hose failures by replacing assemblies at regular intervals, using a schedule based on usage data or past experience,” said Doug Jahnke, Eaton product marketing manager. “As a result, a large number of perfectly good hydraulic hose assemblies are discarded long before the end of their useful life out of fear that they might fail. The LifeSense hose allows the user to utilize virtually all of the useful life of a hydraulic hose assembly, more than 50% longer life in a typical lab test, thus saving on replacement costs and associated downtime while providing peace-of-mind that productivity will not be impeded and safety not compromised by unpredicted hose failure.

The initial LifeSense hose offering will include the widely-used -8, -12 and -16 two-wire hose assemblies. Eaton’s LifeSense hydraulic hose condition monitoring 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.
