Consider the lowly pressure gauge. Consider it well. From it, all of the control and automation in process industries follows as a logical progression. Happy birthday to the folks who started it all.
Here's the press release:
Ashcroft Inc. Celebrates a Milestone
160 Years Strong
In 1852, the burgeoning use of steam power led Edward Ashcroft to produce his first revolutionary "Bourdon tube" pressure gauge. With the growing need for more accurate and reliable instrumentation, Ashcroft(r)
gauges soon became a staple on board steam ships, railroad locomotives and in industries throughout North America.
160 years later, Ashcroft Inc. produces a complete line of state-of-the-art electronic and modern
mechanical instruments under the Ashcroft(r), Heise(r), Weksler(r) and Willy(r) brands. An international network of manufacturing, assembly and distribution operations have extended the availability of Ashcroft products to nearly every corner of the globe. Visit www.ashcroftinc.com

So, since you aren't a wrench jockey watching a dial pressure gauge any more, give thanks to Edward Ashcroft, who started us all on this journey.
