The ultrasonic probe can be placed on the animal's back--the part used in rib-eye steak--to see how lean and muscular the animal is, as well as how much marbling it has.
Operation of this handheld gauge is simple: the operator places an ultrasonic probe on the casting and enters its known thickness during the calibration process.
Krautkramer Branson Inc., best known for its ultrasonic probe and electronics expertise, and ABB NDE Products, best known for its AMDATA ultrasonic imaging systems and scanners, have joined forces in the production and marketing of ultrasonic imaging systems.
"Though we're now evaluating the method on steam turbine bearings," says Armor, "I don't see a limitation to this method in terms of wear, so long as you have adequate access to put in the ultrasonic probe. It just becomes an engineering challenge to get it in place." This method can be used on slider-type journal bearings and thrust bearings.
