Detecting dangerous gases to improve safety and reduce emissions
The primary advantage of differential optical absorption spectroscopy is its scalability. Two elements are required: a calibrated light source tuned to emit a specific wavelength, and a receiver able to read the same wavelength. In some cases, the receiver must also read a reference source for comparison. The two elements can be within the same housing to function as a point detector, but the source and receiver can also be separated, sending a beam across an open path, looking for a cloud of the target gas to move into its field of view.
New Ultrasonic Welder Mode Uses Real-time Adjustments to Improve Welds
Ultrasonic welding, including the single-parameter weld modes, let electronics manufacturers meet high levels of assembly quality, especially for products built from rigid, molded plastic components. But companies that assemble products from components with more dimensional, flexural, or material-related variability have faced a tougher challenge, one typically met by in-house modifications to ultrasonic welding equipment.
To use a welder equipped with dynamic mode, operators select the single-parameter weld mode that provides the best application results to date. Then, they enter two application-specific “scores,” which act as limits for dynamic mode activity. The first is a material “density” score that characterizes the hardness or resistance of the material that is to receive the welded, staked, or inserted part. Low density scores equate to harder, more resistant materials. The second, the “reactivity” score, affects the reaction time needed to get the desired density setting. In operation, dynamic mode monitors each weld cycle, using the density and reactivity limits to adjust and improve the cycle in response to specific part-to-part variabilities throughout the production run.
Gaining an Edge on Line Control
Edge control provides access to real time OEE and information visualization that changes the value calculation. With edge control, end-users can easily tie together existing equipment, other legacy controllers and new external sensing. The combined raw data can be analyzed at the edge to generate information needed by operators to take fast informed action, and it is the foundation for more advanced production line integration, with the ultimate goal of insight-driven and adaptive operation.
Evolving control systems are key to improved performance
For decades, the control system was constrained by physical hardware: hardwired input/output (I/O) layouts, connected controllers and structured architectures including dedicated networks and server configurations. Now, the lower cost of processing power and sensing, the evolution of network and wireless infrastructure, and distributed architectures (including the cloud) are unlocking new opportunities in control systems. Additionally, emerging standards for plug-and-produce, such as advanced physical layer (APL) and modular type package (MTP) interfaces, will drive significant changes in the way plants design and use control systems over the next decade.
How Augmented Reality Became a Serious Tool for Manufacturing
Making monsters appear in games like Pokémon Go is not the only application for augmented reality these days. Industry is using the technology too, harnessing CAD data for training workers, standardizing workflows, and enabling collaboration.
Sensor Fusion: The Swiss Army Knife of Digitalization
With the proper communication protocols and network architecture in place, smart sensor technology and the data it provides can be the bulwark on which digital transformation is built.
If industrial control systems are the brains of a plant, then sensors are its eyes and ears. Simply put, without sensors there would be nothing for SCADA, DCS, or PLCs to respond to. That’s why increasingly intelligent or ‘smart’ sensors packing more onboard processing power, the ability to monitor new variables, and digital communication capabilities are playing such an important role in helping plant operators and enterprise level planners alike to see better and respond to problems with more finesse.
