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

Key

y Kg/m

, specific weight of air

m/s, air speed

g 9.81

m/s

gravity acceleration

mm C.A., dynamic pressure

Measuring total pressure
