Dear Dilberts ,
have this to solve :

Air is present in a silicon tube with about 3mm inner dia (expandable to
5-6mm inner dia) ,
ending with a very sensitive pressure sensor (medical app) .
The air does not flow, just measures pressure .
The sensor is soo touchy i have to even out the readings to prevent it from
alarm set at every jitter of atmosphere,
while retaining the continuous linear read out .

Therefore i'd like to insert a say 1/8 dia dense ceramic filter pellet into
the airpath ,
in order to muffle the peaks and maintain the mid line readout .

Could anybody point me where to get a relatively not much porous, hard, non
shedding ceramic filters,
1/8 - 1/4 dia/cylinder/conus, please , in thousands and cheap , obviously .

I thought of rambling pellets of higher order (precision machining/jewelry),
if they'd be air permeable sufficiently ; any idea appreciated .

Cer filters would be easy on production , packed silicone foam inserts would
take more of dexterity ,
which is why i'd prefer a hard substance .
On lesser materials i'd fear life deterioration (7 year design)


Thanks a lot                       paul
