Re: Oct 8 - Part I: Sensor Specs 101

NO RATINGS
Randy, the slides showing difference on accuracy and precision are the best explanation I have seen on the subject. One related thing not covered, and often misunderstood is resolution, i.e. number of bits/digits. Maybe you could discuss in the chat session.

I did not resolution have on the slide but did mention that resolution (specifically for digital output sensors) is impacted by the number of bits of the A/D conversion. It is representative of precision for the digital sensor. The quantization error is reduced by increasing the bit rate and the cost goes up as well. For an analog sensor with a continuous output, precision is a little more straight forward.

Latest Analysis
Here are some of the top-paying jobs available to engineers as they grow in their careers.
As manufacturers add new technologies to their products, designing for compliance becomes more difficult. Prepare for the certification testing process. Otherwise, you increase the risk of discovering a safety issue after a product leaves the assembly line. That will cause significant time-to-market delays, be much costlier to fix, and damage your brand in the eyes of customers. 
Stratasys will be exhibiting two groundbreaking large-scale additive manufacturing technologies, as well as other new products, next month at the International Manufacturing Technology Show (IMTS) in Chicago.
Ford Motor Co. announced plans last week to join an ever-growing number of automakers who intend to produce fully autonomous vehicles in the next five years.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
