In the hot seat
So we've got pressure, flow and level measurement under our belts (see Plant Engineer, November/December 2008 and January/February 2009). Time to move on to temperature - and although there are very few sensing technologies, there is huge variety in terms of sensor, probe and thermowell constructions, the wiring and the transmitters - all of which play vital parts in getting reliability, precision and safety.
Infrared vessel inspection whatever the scale
Thermal imaging is proving to be a quick and easy way of monitoring the integrity and content level of storage tanks. And now there are several infrared technologies that can be employed to sense particular gases, such as VOCs
Testing times
The power of sensing systems today is to be found less in the range of techniques, technologies and hardware designs, and more in their on-board software. Brian Tinham reports

Staying skilled
All forms of engineering require precision. Technological advancements are aiding employees with their measurement work, but learning and retaining practical measurement skills is also a must, as Adam Offord discovers

The heat is on
There is a world of difference between art, black art and science, but thermal cameras are ready to move from the former to the latter. Brian Tinham explains
