12:19 AM Jak_o_Shadows: how does it work?
12:50 AM rue_bed: do you know about differential transformers?
12:50 AM rue_bed: lvdt?
01:06 AM rue_bed: well, its not that
01:06 AM rue_bed: its a differential capacitor
01:06 AM rue_bed: much easier to operate
01:06 AM rue_bed: much larger signal off the sensor
01:07 AM rue_bed: and you dont need any chips to drive it
01:07 AM rue_bed: my bench test is doing delta 1.4V over 11mm
01:07 AM rue_bed: too much if I use an avr with internal 1.1V ref
01:08 AM rue_bed: tho I suppose I could scale it , hmm
01:10 AM rue_bed: I think I'd like to put a 4-20mA output on it
02:06 AM Jak_o_Shadows: is that analog or digital, to get to the 4-20?
08:57 AM rue_mohr: its analog
08:57 AM rue_mohr: the sensor itself gives you an output of about 1.4V
