What is static pressure on a transmitter?

We call static pressure the highest pressure applied in any of the sides of a pressure sensor.

Notice that, the differential pressure could be zero. This implies that the pressure in the low and high side of the pressure sensor are the same. However, this does not means that the static pressure is withing the limits of the transmitter sensor specification.

Consequently, the pressure in any of the sides cannot surpass the limit of the static pressure value assigned by the sensor manufacturer.
