Thanks a lot folks , did get very good leads from Phil & Joyce ,
but my hat & scalp (not quite a show piece) goes down to Roger,
for dead-on insights & pulling me quick smart out of hot waters :

'm sure there's few of us with this applications.

ps
Steve's right, this Net 's just about only one working,
spent some time lately outside, with pitiful results

> Air is present in a silicon tube with about 3mm inner dia (expandable to

> The air does not flow, just measures pressure .
> The sensor is soo touchy i have to even out the readings to prevent it

> while retaining the continuous linear read out .
>
> Therefore i'd like to insert a say 1/8 dia dense ceramic filter pellet
