Hi Roger,
For retrofitting such a device it could be more convenient to mount it
behind the cockpit where the TE plumbing first meets the light of day
and the length of our arms :)
Would there need to be one per vario? Unless the components were
standardised, there probably would. Most loggers use the Intersema
transducers these days but there are several other types around.
Cheers

With the general progress away from flow based variometers (electric
and otherwise) where doing away with the problems of flasks seems
beneficial, surely the next step is to get rid of the flexible plastic
plumbing from the TE head on the fin LE to instrument panel. It can't
help to have the flexible plumbing moving during gusts and pull ups as
the movement can induce unhelpful volume changes in the line, albeit
that they might be small, which alters the signal. With power and
data wiring to the fin, the pressure transducer unit could sit in the
fin in a waterproof accessible location. Then the pressure transducer
would see raw data from the TE head better but then perhaps the signal
filtering may be more challenging. Or does the long plastic pneumatic
line act as a signal damper in a useful way?
Just a query for a slow Monday morning. Maybe someone out there has
attempted this approach?
