Digital Measuring Devices (Part 2)

In Part 1 of this article, we saw that one of the basic methods by which a digital measuring device operated was the conversion of an analogue signal (often a voltage or an electric current) into a set of digital bits. The number of bits determined the precision with which the device could take a measurement. The article went on to describe the workings of a digital thermometer and how domestic-quality thermometers are often designed around the use of degrees Celsius with displays in degrees Fahrenheit being an add-on where the Fahrenheit display is calculated from the equivalent Celsius measurement.

In this article we will look at how digital weighing devices work.

Digital Measuring Devices (Part 1)

In this two-part series, Martin Vlietstra will be looking at how digitisation is applied to measuring devices:  In Part 1, he will examine what “digitisation” is and explain how it is applied to thermometers. In Part 2, he will look at how it is applied to weighing devices.

Our awkward, dual measuring instruments

As a consequence of the “very British mess” with measurement policy, the public has to put up with awkward, cluttered, hard-to-read dual measuring instruments. Various types are used every day. In this article, Ronnie Cohen describes several examples and comments on their impact on our daily lives.
