Magmeters
Magmeter – Magnetic Flow Metres How do you measure flow through a pipe? It’s a trickeier problem than it initially sounds. It’s also a question with many answers. Many approaches centre around pressure transducers measuring total pressure and static pressure to then infer dynamic pressure and therefore fluid velocity. Although this means that the density…

Thermocouple
The Thermocouple Many of the transducers we’ve looked at over the last few weeks really are not transducers in the strictest sense, they don’t change a form of energy into another. Other items we’ve looked at, tend to exploit electro-magnetism and changes in fields to produce measurable results, all interesting and fascinating in their own…

Strain Gauges
The Strain Gauge The humble strain gauge, technically, speaking, is not a transducer as it doesn’t transfer energy from one form to another. However, given it is fundamental to a wide range of engineering analysis in the modern world, and Flintmore have extensive experience working with them, it felt wrong to exclude it from transducer…

Proximity Probes
Proximity Probes Proximity sensors are all around us. Most of us carry a device with several of them in our pocket, but few of us know how they work or have given them a second (or even first) thought. Measuring distance electronically is far less practical than we would initially think. For something so easy…

The Galvanometer
The Galvanometer One of the earliest and most significant transducers used for instrumentation is the galvanometer. Practically, it is one of the most important inventions ever produced by humankind, but it had rather humble beginnings. Its first, and rather gruesome form, was the frog leg galvanoscope. Many of us have heard that one of the…
