Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...

An only slightly less simple followup circuit also ratios sensor capacitance to a reference capacitor to measure micrometers…this time linearly. Figure 1 The U1a and U1b cross-coupled Schmidt trigger ...

Standardization might sound boring, but it’s really a great underlying strength of modern society. Everyone agreeing on a way that a certain task should be done saves a lot of time, energy, and money.

Single-use biomanufacturing has shifted the default expectation for process monitoring: instead of pulling manual samples and waiting for offline analysis, modern disposable bioreactors arrive with ...

Access to safe drinking water remains a global challenge. A low-cost, self-powered floating device points to a new direction in smart water treatment by unifying contaminant detection and disinfection ...
