Join us for a webinar on 27 April, and learn how you can improve overall equipment effectiveness (OEE) by bridging the gap between your existing industrial assets and the digital world.
Process control systems are used in everything from advanced manufacturing to run-of-the-mill activities at home, like heating your house and brewing your beer. (You do brew your own beer, don't you?)
A control system that manufactures a product requires monitoring and control of many different process variables, while some at home require little more than a timer. For example, in manufacturing we may use flow meters to make sure fluids flow through pipes at a certain rate, or float meters to ensure ingredients fill a vat to a specified level.
When I brew beer at home, I may use a temperature sensor in my mash tun, wired to a controller that’s controlling my heating element to keep the mash tun at just the right temperature for optimum starch-to-sugar conversion. This is an example of a closed-loop control system.
(To see how small closed-loop control principles are scaled up to build industrial process control applications, check out the New Belgium Brewery case study and see how they use Opto 22 gear to brew their world-famous Fat Tire and other beers.)
Although their cold storage rooms were automated, on weekends operators used to have to stop by the company's factory to verify that systems were running and temperatures were within range.
It's the international trade fair for industrial automation: Industrial Automation North America (IANA).
And here's an even bigger reason to attend: IANA is co-located with IMTS 2016, North America’s leading manufacturing technology trade show.
CalCA builds produce storage systems for growers in California and all over the world. Each system must be flexible to accommodate fluctuating harvests and individual produce varieties.
ATEX is the name commonly given to the two European Directives for controlling explosive atmospheres in workplaces.
Several Opto 22 products are now approved for both standards and offer you options for applications in potentially explosive areas.
In fact, CalCA's industrial refrigeration systems for storing produce can be found throughout the world, reaching to India and China.
Way back in 1883, the Frick Company started manufacturing refrigeration compressors. During the next 100 years they became well known for a variety of reliable refrigeration system components.
By the 1980s Frick began automating their systems with Opto 22 products, and they began to notice a new need in the industry: custom system design and integration.
A lot of control engineers do, especially in fields like water treatment, refrigeration, thermoforming, refining, food processing, and energy or building management.
There are a variety of temperature sensors on the market—ICTDs, thermocouples, RTDs, thermistors, infrared sensors. Accuracy, cost, wiring complexity, and environmental conditions are some of the factors that determine which one is best for your application.
The biggest user of water in our house is not human:
A web browser is installed on most of the key devices we use every day. PCs, smart phones, tablets, even our TVs now have a modern web browser installed. I can even surf the web from my Android smart watch (a Moto360).
It makes sense then, does it not, to view everyday data on an interface that we use every day?
How much water flows through our house was the subject of last week's blog... It both surprised me and pleased me to find out that the biggest user of water in our house was not a human.
