Choosing the Right Touchscreen Display Technology for Your Control/Automation Process

From industrial panel PCs, to open-platform graphic operator interface terminals (OITs), to microOITs, to human-machine interfaces (HMIs), there are many choices of interactive display technologies for manufacturing and process control. It can be a challenge to decipher the right product for the right application — even for the more technically minded individual, let alone the business owner who simply wants his process automated. The best way to get a handle on these products is to categorize them and then describe each group.

Using Micro OTDRs to Test Fiber Optic Networks

Uses for traditional optical time domain reflectometers, or “OTDRs” include the certification and troubleshooting of very long-haul fiber optic networks such as campus and metro networks. In many LAN, WAN or FTTH environments, however, fiber links are relatively short and, therefore, usually operate over multimode fiber cables at wavelengths of 850nm and 1300nm. A new generation of “Micro OTDR” is ideally suited for this application, which typically has a maximum range of about 25 miles.

Reinventing Disease Detection and Diagnosis

As devices for disease detection and diagnosis become more advanced, they also are becoming smaller. Next-generation technologies for faster detection of diseases such as cardiovascular disease, melanoma, and breast cancer are handheld devices that are easy to use, portable, and more accurate than many of the currently available diagnostic tools. As the following examples illustrate, immediate diagnosis and detection of life-threatening diseases may soon be held in the palm of your hand.

Benefits of Magnetostrictive Sensors for Industrial Applications

Modern industrial machines rely on fast, accurate motion control in order to achieve high product quality and productivity, as measurement errors can lead to increased scrap and production downtime. However, these and other costly headaches can be avoided by choosing the proper position-sensing device for your application.

All Motors are Stepping Motors

In 1938, General Electric began producing a two-phase synchronous induction motor which, at 60 Hz, ran at 75 RPM. The low speed resulted from using a different number of rotors to stator poles or teeth, which made the motor a good bi-directional control motor. This motor was used by Superior Electric Company of Bristol, CT, to run power driven autotransformers used to dim lights in auditoriums and similar applications. General Electric ceased producing this motor in the mid 1950’s due to slow sales.

Intelligent Control Increases Motion System ROI

The economic realities of the industrial marketplace are driving machine builders and integrators to get creative and build more intelligence into their machines in order to increase productivity and lower lifecycle cost. This is done by minimizing time to communicate with the motion controller, and by setting up and optimizing the closed-loop controls that squeezes the last few unneeded time cycles from a machine operation. Therefore, by looking at how a motion controller connects, controls, and can optimize a system, the best performance per dollar invested can often be accomplished.
