The Increasing Use of Electrical Actuators in the Aerospace and Defense Industry

Hydraulic and pneumatic systems have traditionally been the market leader in providing power in the aerospace and defense industry because of their low cost and high power density. But in recent years, attention has been focused on the limitations of hydraulic actuators, including their weight, performance, and high maintenance requirements, as well as concerns over their vulnerability due to security issues and other risks.

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.

3D Machine Vision Using Laser Triangulation

Applications for 3D machine vision are rapidly expanding in a variety of industries for several reasons. The first is that vision systems can lower production costs by increasing yields and/or reducing scrap product and wasted raw material. One example of this would be extruded products from various materials (rubber, plastic, metal), where it’s vital to know as soon as the process goes out of specification.
