Dear Bill,

ISSYS Inc. is specialized in high-peformance pressure sensors.
currently we are developing (and soon will manufacure) ruged,
ultra-senstive pressure sensors for semiconductor equipment industry.
Please check our web site, http://www.mems-issys.com/

We may be able to design and develop a custom sensor for yur application.
If you're interested, we can talk further.

thank you
Nader Najafi
