I'm ahead of the curve, it seems. A few years ago, I used the hall-effect to sense current in a 3-phase DC motor (for a fuel pump on a UAV). It worked out well for the application.

I just finished a current sensing application last Summer.  I've been itching to use a Hall effect since then, but haven't had a chance.  Having an isolated solution with no power draw would have been beautiful on my last product.  NVE has some great products to use, as well as a part that includes a current trace inside the package.

Excellent article. Low cost, good power management and compact design are all compelling advantages for these applications.  Along with the control advantages of course.  Will be interested to see specific applications that can use this technology.

This is exciting. Current sensing is becoming more and more critical in applications requiring the most efficient systems to report back valuable information on loads. I am happy to see there are companies out there gaining interest in this sort of IP so I would forecast a step towards increased resource conservation. Considering how efficient EV's and self-sustaining industrial buildings have become in recent years, the sensor market can only be breaching the threshold of impressive expansion; since most cars on the road still pollute with combustion engines and many factories herein carry the same output characteristics, I would be surprised if this market picks up speed.

Industrial workplaces are governed by OSHA rules, but this isn’t to say that rules are always followed. While injuries happen on production floors for a variety of reasons, of the top 10 OSHA rules that are most often ignored in industrial settings, two directly involve machine design: lockout/tagout procedures (LO/TO) and machine guarding.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
While risk management sounds like one activity, in order to be conducted effectively, it must be broken down into three sub-components: risk assessment, risk monitoring, and response planning.
While many larger companies are still reluctant to rely on wireless networks to transmit important information in industrial settings, there is an increasing acceptance rate of the newer, more robust wireless options that are now available.
To those who have not stepped into additive manufacturing, get involved as soon as possible. This is for the benefit of your company. When the new innovations come out, you want to be ready to take advantage of them immediately, and that takes knowledge.
