OVERVIEW
What it does and why it is built this way
The PR-310 measures the difference between two pressures, which makes it the standard choice for flow across an orifice, filter condition and hydrostatic level.
A capacitive cell with a fully welded isolating diaphragm gives high accuracy on spans as small as 10 mbar and survives static pressures up to 160 bar.
