How can we say this current sensor doesn't measure DC?
Digikey is saying this current sensor "CS0305B" from CUI Devices can measure AC and not DC.
But in datasheet there is no reference or note mentioning this current sensor will not measure DC.
...

What does sensitivity mean for a current sensor when given in "mV/N" or "mV/mT" rather than "mV/A"?
I have been analyzing various datasheets of current sensors and majorly getting sensitivity given in "mV/A," from which I understand the output voltage per 1 ampere. I do not understand it ...

Why most non-invasive current sensors have a minijack at the other end?
If I search on google for non-invasive current sensor and click on the images tab, in most cases, I see a minijack at the other side of the wire.
What is the reason for this? Is this minijack supposed ...

Measuring high currents with toroids
I got a PT27312 current sensor (datasheet), I wonder if I can use it to measure currents up to 100A AC/DC.
I couldn't find any specifications in respect of the current measurement range.
I only know ...

How to connect multiple sensors to single PLC input?
Hello. I have a scenario where I have multiple PNP "error signal" from several sensors (let's assume 3 for now). If the sensor output is HIGH, then there is error. If the sensor output is LOW, then ...

Inexpensive field deployable non-invasive current sensor [closed]
Is there an inexpensive way to MacGyver a non-invasive current sensor together in a field (yes, a literal field), assuming some prior planning?
The context here is an event similar to EMF Camp or OHM,...
