The new sampling/sensor initiative (NeSSI) is moving steadily to fulfill its original promise of increased efficiencies, costs-savings, and micro-analytic capabilities despite recent growing pains related to fieldbus.
Carefully managing compressed air can save money. Compressed air is often overlooked in energy studies because many people do not fully understand compressed air equipment, their own system, or what it costs to produce compressed air power.

Theres no simple solution to achieving accurate temperature measurement. Its a combination of knowing the inherent accuracy of particular sensor types, and how environmental factors can create further measurement uncertainty and the sensor calibration techniques available to reduce this uncertainty.

As the pharmaceutical industry has matured, concerns about the safe handling of drug compounds during the manufacturing process have increased. To meet exposure limits and protect batches from any kind of contamination, the industrys need for improved containment has increased.
Removing water or moisture from a liquid stream is a critical operation in many processes. Liquid stream dryers commonly contain either molecular sieves or adsorbents; during the last 20 years, the use of molecular sieves has become much more common.
