We see from your search that you're looking for information on the term "Differential Pressure",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release Airflow sensor isn't so dusty from
TTI Europe, which we summarised at the time by saying "MEMS-based airflow sensor delivers one-way or bidirectional sensing with amplified output in a highly compact package".
Earlier in the week,
we featured the news release Switch ranges go way beyond pressure from
PVL: "PVL reckons it can supply the most extensive range of pressure, vacuum, level, flow and temperature switches available".
In November 2007, we covered the news from Beko Technologies
concerning its Oil Control
- take a look at Sensors monitor oil in compressed air
which says: "Oil Control does not react to the rise of the differential pressure, instead monitoring changed remainder oil rates in the streaming compressed air".
Take a look also at the news release from Able Instruments and Controls, Field instruments chosen for gas project,
as well as Pressure sensor monitors filter cleanliness from American Sensor Technologies,
and Pressure transmitters resist corrosion from ABB Automation Tech (Instrumentation + Automation).
