Ultrasound measures tiebar stretch.A new handheld troubleshooting system from Hydratight of Houston takes an unusual approach to measuring tiebar stretch on molding machines. Foregoing the usual hydraulic and mechanical measurement methods, the Boltscan system relies on an ultrasonic "pulse-echo" technique, which senses tiebar stretch from changes in a sound wave's time of flight through the metal. According to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. market development manager Jorg Albrecht, the device is "far more sophisticated" than a simple thickness gauge. Before taking any measurements, users program Boltscan by downloading a tiebar's physical-property and dimensional information from a personal computer. Boltscan then measures and saves reference length of the tiebar while it's in a slack state. Once the clamping cycle has begun, the tiebar measurement is repeated to yield a relative elongation elongation, in astronomy, the angular distance between two points in the sky as measured from a third point. The elongation of a planet is usually measured as the angular distance from the sun to the planet as measured from the earth. reading. The device can also tell users if elongation falls within pre-established limits. "This is a very useful function since it allows the unit to be used as a go/no-go gauge to check tie-bar stress," says Albrecht. Relative accuracy is better than [+ or -]0.5%, he reports. In return for a price premium over other measurement methods, users get a system that's reportedly far easier to install and to use. Aside from a hand-held computer Noun 1. hand-held computer - a portable battery-powered computer small enough to be carried in your pocket hand-held microcomputer portable computer - a personal computer that can easily be carried by hand and a short cable, Boltscan's only external component is a small magnetic transducer transducer, device that accepts an input of energy in one form and produces an output of energy in some other form, with a known, fixed relationship between the input and output. about the size of five stacked quarters. "As quick as a mechanic can touch the transducer to the end of the tiebar, installation is complete," says Albrecht. What's more, all calculations are performed automatically; measurements simply pop up on a digital readout (1) A small display device that typically shows only a few digits or a couple of lines of data. (2) Any display screen or panel. . The Boltscan system first saw use in the power and petrochemical industries, but Hydratight has yet to make any installations in injection molding injection molding n. A manufacturing process for forming objects, as of plastic or metal, by heating the molding material to a fluid state and injecting it into a mold. . However, Husky Injection Molding Systems Ltd Husky Injection Moulding Systems Ltd was founded by Robert Schad, a German immigrant who came to Canada in 1951 with $25 borrowed from an uncle and a letter from a family friend by the name of Albert Einstein. . has started to evaluate the system at its Bolton, Ont. plant. Don't be surprised if machinery OEMs and larger molders make up Boltscan's main user base. The system costs $10,500. |
