Duct pressure switches and sensors

Installing differential pressure probes for air

A - Control a filter (clogging)

B - Control a fan (upstream/downstream)

C - Measurement of difference in pressure between two ducts

D - Measurement of difference in pressure between two rooms or 

of inside of duct and outside

Basic principles

Measuring static pressure(i.e. pressure exerted by air on pipe 

walls)

 

Measuring dinamic pressure 

Legend

y

Kg/m3, specific weight of air

q

m/s, air speed

g

9.81 m/s2 gravity acceleration

Pd

mm C.A., dynamic pressure

Measuring total pressure
