Mahr Federal'sMarCheck measuring and evaluation unit is for its high precision Linear100 universal length measuring instrument. MarCheck allows both measurementsand calibrations to be performed quickly and reliably at the touch of a button.Results are shown in large digits on the display screen and can be output viaUSB or RS 232 ports. With a direct measuring range of up to 50 mm (2 in.) andan application range of up to 100 mm (4 in.), the Mahr Federal Linear 100provides internal and external measurements directly on the shop floor.
Easy-to-usemenus guide operators, and measurements are performed systematically usingfunction keys. The Linear 100 withMarCheck offers analternative to rings and gage blocks for shop-floor mastering of inner andouter comparative measuring equipment, 2-point measuring instruments, insidecalipers and dial comparator snap gages. MarCheck upgrade packages are alsoavailable for older length measuring machines.
The Linear 100 has an adjustable 76x 76 mm (3 x 3 in.) measuring table for precise adjustment of part position whenmeasuring ODs and a 4 to 40 oz (1to 11 N) adjustable measuring force that remains virtually constant over theentire measuring range. For ID measurement, the 100 mm (4 in.) x 185 mm (7.3in.) worktable allows for precision part positioning for measurement. Theintegrated measuring system is based on the Abbe principle (i.e., the measuringarm and reference are in line) which eliminates cosine errors.
Internal/External measurements, as well as Combined Internal/External measurements, are possible without remasteringand easily interchangeable measuring anvils provideincreased part measuring versatility. The solid cast body reduces stresses and twisting error and a large digital display provides clear readouts withselectable ID/OD results and preset values. An RS-232 interface makes it easyto transfer output data to PCs, and optional software allows measured values tobe transferred to Windows programs such as Microsoft Excel.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
