Influence of the static
pressure
Note!
The influence of the static pressure on the zero point can be calibrated out.
Total Performance The "Total performance" specification comprises the non-linearity including hysteresis, non-reproducibility, the
thermal change of the zero point as well as the influence of the line pressure p
st
.
The line pressure p
st
is 70 bar (1050 psi) for the 100 mbar, 500 mbar, 1 bar, 3 bar, 16 bar und 40 bar measuring
cell.
