Double bourdon system differential pressure gauge are designed to measure difference between 2 pressures.It can be used in corrode environments.

The instrument has 2 independent measuring systems.The measured pressure deflects the elastic elements,displacements then take place to actuate gear mechanisms through linkages to carry 2 pointers traveling over instrument dial, and an auxiliary dial shows the pressure difference.
