That's all they (surplus computer junk store) got
right now; next month who knows? If by electronic
sensor you're referring to digital-coded output,
then decoding it becomes an issue. A
potentiometer type device means that the meter
circuit is passive (resistance bridge).

These places never have a clue. Wherever it came
from, it was long ago, judging from the dust!
This place is cool. You know that aluminum hinge
you use on the doors that seems like it won't last
long in service? This month they got in the steel
equivalent -- $1.00 for four.
