nice find . . .

Been a fan of amploc sensors for decades. Used them
on several projects at Beech and the price is sure
right!
The do take a small 'set' such that the zero
current offset changes a tiny bit when used
in a bi-directional measurement situation.
But that's a 'battery' ammeter which is a tiny
step above useless. For uni-directional
current measurement, they're pretty functional.
Here's one left over from a Beechjet
trim system study.

I used to brass-board a gain/offset
circuit onto a piece of ecb so that
it would directly interface with an
input to my data acquisition system.
