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…

The GM Tube
The Gieger Muller Tube The first transducer we’re looking at as part of our series on transducers is the GM Tube. You might not know what a GM Tube is, or even what they look like, but you almost certainly know what one sounds like. A slow-clicking sound in the background suddenly rises to a crescendo when…
