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

Diversified industrial manufacturer Eaton Corporation today 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, will be introduced to

the North American market at the International Fluid Power Exposition (held in conjunction

with ConExpo 2011) in Las Vegas, March 22 - 26, and to the European market at Hannover Messe

2011 in Hannover, Germany, April 4 - 8.

    "Hose failures in the field present serious safety issues, environmental concerns and

result in unscheduled system downtime, all of which have serious economic impacts."

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 percent 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.

"Additionally, hydraulic hose failure is one of the largest causes of unplanned maintenance

events," Jahnke said. "Hose failures in the field present serious safety issues,

environmental concerns and result in unscheduled system downtime, all of which have serious

economic impacts."

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.
