Portable power stations are more powerful and cost effective than ever before. And, thanks to advances in lithium-ion battery ...

Abstract: This article proposes a nondestructive multichannel sensor for liquid-level detection based on spoof surface plasmon polaritons (SSPPs). A mathematical model for liquid-level sensing is ...

Point level switches preventing overflow are typically placed in a position where they should seldom or never be used. These switches are often called High High level because they are above the stop ...

Recently I came across some non-contact liquid level sensors and gathered them out of curiosity. They have been available in the market for the past few years, but this time I was lucky enough to get ...

Process Sensing Technologies (PST) has recently launched a range of intrinsically safe optical liquid level switches. Using innovative infrared technology and the principle of total internal ...
