Hello:

I'm looking for info (reading, app notes, etc) on a Blumlein Bridge or
other methods associated with detecting changes in various capacitance-
transducers. I believe it is in the category of 'self-balancing
bridge'.

Any help would be appreciated...

Thank you

What do you need to know? I first got to know about if from K.H.P. Neubert's
book "Instrument Transducers" published by Oxford at the Claendon Press in
1963, which sttod me in good stead when I went to work at EMI Central
Research in 1976 - Percival had worked with Blumlein back in the 1940s.

Kibble and Rayner's "Coaxial AC Bridge", published by Adam Hilger in 1984 -
ISDN0-85274 - contains a lot of useful stuff, though it is written for
national standards laboratories and doesn't shy away from labour-intensive
solutions. Incidentally the "Coaxial"in the title was intended to mean that
the authors were talking about fully shielded structures, rather than
transmission line transformers.

If you can tell us more about your application, we might be able to come up
with something more specific. If you don't want to reveal too much on a
public user-group, you could e-mail me at billdotslomanAtieeedotorg.
