Ground-Isolated Pressure Sensor


The use of highly-sensitive piezoelectric combustion pressure sensors with built-in ground isolation can largely avoid the effects of electrical interference. The isolation of the sensing element prevents the generation of noise currents and allows interference-free measurements, even if potential differences exist between the engine and the measuring system. The new Kistler Type 6125C is the third generation of a combustion pressure sensor with built-in ground isolation. The use of a new Kistler PiezoStar crystal has made it possible to increase the sensitivity to –37 pC/bar and the pressure range to 300 bar. This innovative sensor ensures precise and reliable measurement data even under noisy testing conditions ...

Torqing Sense for Process Plant Control


These sensors are tracking every little change in the plant’s operating parameters, indictative of either the state the materials being worked or of the state of the machinery itself. For instance an increase in torque on a mixer drive may suggest that a mixture within is thicken up as expected, or alternatively that a seal or bearing is sticking and may soon fail altogether: either way this is vital information for the central computer to capture and assess. The TorqSense unit emits a low powered radio frequency signal towards the combs, which reflect it back to the TorqSense. The reflected signal comes back at a changed frequency, the change being propotional to the distortion of the combs, and thus to the torque in the drive shaft ...

Sapphire Window Optical Process Probe


The SWOPP03C Sapphire Window Optical Process Probe, from Celsum Technologies, is a robust transmission probe with a 600 micron internal glass fibre and a SMA 905 standard optical connector. The SWOPP03C probe has an extended profile, to be compatible with earlier generations of probe, and has a polished sapphire lens sealed into the type 316 stainless steel body, to give an essentially chemically inert, abrasion resistant interface to the material under test. The integral SMA 905 connector allows the probe to be screwed into the transducer port on the processing line before connection to the fibre optic cables, thus easing in-service removal and insertion into existing installations ...

Nine Awards for New Research Projects to Develop Advanced Sensing Technologies


7 January 2009 - The National Institute of Standards and Technology (NIST) has announced nine awards for new research projects to develop advanced sensing technologies that would enable timely and detailed monitoring and inspection of the structural health of bridges, roadways and water systems that comprise a significant component of the nation's public infrastructure.


The awards are the first to be made under NIST's new Technology Innovation Program (TIP), which was created to support innovative, high-risk, high-reward research in areas of critical national need where the government has a clear interest because of the magnitude of the problems and their importance to society. The cost-shared awards initiate up to $88.2 million in new research over the next five years on structure monitoring and inspection technologies, $42.5 million of it potentially funded by TIP ...
