How automation can best affect the ratio that defines energy efficiency

Energy management and energy efficiency are key elements of the desired objective, and automation professionals can do their part by acting not only on the numerator (work required) but also on the denominator (energy supplied or inputs), says Ian Verhappen.

Energy Efficiency MN1

Energy efficiency continues to be a top-of-mind topic driven by the focus and debate on renewable and alternate energy and the migration from “bad” sources of power such as coal and other greenhouse-gas-generating contributors—anything with a C-H chain. We engineers know this is shortsighted since not only are most products we use based on hydrocarbons, but the laws of physics dictate that the closer the source and final use of the energy are, the better. Energy management, on the other hand, is the process of monitoring, controlling and conserving energy in a building or organization. A key part of management is conservation because energy conserved means it…

Voices: Ask The Experts

Ask the experts: Level switch safety; level for flow

Are piezoelectric switches really safe in hazardous areas? How can we use a level gauge to set a flow alarm?

Q: Are piezoelectric switches really safe in hazardous areas? I understand that in the vibrating, tuning fork-type level switch, a piezoelectric crystal is generating an oscillating frequency. We have a Class A product stored in a tank, which requires a Zone 0 installation, and I need a level…
