Siemens SITRANS 7MF03.0 - Absolute Pressure with Front-Flush Diaphragm

Absolute pressure measuring limits from
gauge pressure series
Upper measuring limit 100% of max. range (for oxygen measurement: max. 100 bar/10 MPa/
1450 psi and 60 °C ambient temperature/medium temperature)
Start of scale value Between the measuring limits (continuously adjustable)

2.41 … 72.5 psi a
1 … 30 bar a
0.1 ... 3 MPa a
14.5 … 435 psi a
Depending on the process connection, the measuring span may differ from these values
1)
The MAWP value of the pressure transmitter can be lower than the PN value of the mounting
flange and vice versa. To determine the maximum permissible operating pressure and the
maximum permissible test pressure, use the lowest value as reference.
