Encoders Ensure Position Accuracy of Linear-Torsion Tester

Instron (Norwood, MA) manufactures materials testing equipment and accessories that are used to test samples ranging from components for jet engines to medical syringes. The company’s ElectroPuls systems are used for fatigue testing, which examines the behavior of materials under fluctuating or cyclic loads in the elastic regime. The E1000, E3000, and E10000 fatigue test systems are suited for biomedical/biomechanical research applications, and feature a wide dynamic performance range and low force characteristics. The all-electric systems use linear motor technology to eliminate the need for ball/lead-screws, and enable slow-speed static tests through to high-frequency dynamic tests at over 100 Hz.

Implementing Color Machine Vision Inspection Systems

Color provides critical information that can improve the reliability of many machine vision inspection applications and make it possible to inspect many products that cannot be inspected in grayscale. Typical examples include ensuring that a tan rather than a taupe automotive interior component is installed, and checking the position of a black label on a black single-serving coffee cup.

Motion Solutions for Electric Expansion Valves

Expansion valves are flow-restricting devices present in any refrigeration system. The valve needle remains open during steady state of operation. The size of the opening, or position of the needle, is related to the pressure and temperature of the evaporator. When set and controlled properly, an expansion valve will keep the evaporator active throughout its operation.

Hamburg Airport Relies on Drive Technology to Keep Bags Moving

Hamburg Airport in Germany handles nine million pieces of baggage every year. For the baggage handling staff, the reliability of the conveyor system and the prevention of faults are the highest priorities. The breakdown of even a single component of the system would result in a backlog and unacceptable delays.

Motion Controller Automates Hydrostatic Pressure Testing

A flexible hydrostatic test system for the oil and gas industry must precisely measure a wide range of pressures. Because the items tested vary widely, most testing is done manually. A test engineer sets appropriate parameters, and a skilled operator adjusts the pumping system for the specimen under test. After the technician sets up the test, he or she is usually seated at the pressure source and controls the specified pressure. The human interaction lacks precision and repeatability; each time the test is performed, there is a variation in results. In extreme cases, the maximum rated pressure is exceeded, causing damage.
