Siemens 7MF0340/7MF0440 Difference pressure transmitter
1： Product introduce：
SITRANS P320/P420 pressure transmitters are digital pressure transmitters featuring extensive user-friendliness
and high accu-racy. The parameter assignment is performed using input but-tons or the HART interface.
Due to their advanced diagnostic functionalities according to NAMUR NE107, the SITRANS P320/P420 pressure transmitters
are very suitable for use in chemical plants.
