Current transducers application field

AI Thread Summary
A PhD student is researching improved Hall effect-based current sensors that offer over 400 kHz frequency bandwidth and 0.1% accuracy at a competitive price. The student is struggling to identify market gaps since existing Hall effect sensors already meet many industry needs. There is a request for suggestions on potential industries or applications that could benefit from these enhanced sensors. A response questions the assumption that Hall effect sensors are limited to 250 kHz, citing examples of existing products with much higher bandwidths. The discussion highlights the need for further exploration of unique applications for the new sensor technology.

Hello, guys. My question is related to my research work and I really really need help.

I am a Phd student involved to the work of one R&D department. We are currently working with a technology which allows us to improve the performance of Hall effect based current sensors, in particular we can provide larger frequency bandwidth( >400 kHz) comparing to the Hall effect based (250 kHz), accuracy 0.1% and while remaining at same price range with the hall effect based sensors. While investigating the market needs and applications of the sensors I have faced with a problem that Hall effect sensors cover the needs of the industry pretty well, so no obvious gaps were found. I am not a professional in the field yet, that's why i need help in picking out some potential industries our sensor can be used, with an emphasize on 400 kHZ of frequency bandwidth and 0.1% of accuracy. It is a part of my future thesis, so I really will appreciate any help/advice. May be you can give me some hints what application can really benefit from it? Or may be someone just can share his opinion?


Thank you for the collaboration.

Welcome to the PF.

Are you sure that Hall effect sensors are currently limited to 250kHz bandwidth? Tektronix' line of clamp-on current probes have bandwidths in the 100's of MHz:

And I believe they use Hall sensors, since they work down to DC.
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
