Siemens P320 Pressure Transmitter 7MF0340-1HM01-5AF2
SITRANS P320/P420 series pressure transmitters are digital
instruments characterized by user-friendly interface and high
accuracy. Parameters can be set via local pushbuttons and HART
fieldbus communication. The wide range of functions makes the
pressure transmitters very suitable for the needs of the plant.
Despite the large number of setting options, operation is simple.
The SITRANS P320/P420 pressure transmitters are ideally suited for
applications in the chemical industry due to the self-diagnostic
function in accordance with NAMUR NE107*. Powerful self-diagnostics
and storage of process variables ensure that the SITRANS P420 is
“ready for the digital age”. The “Remote Safe Commissioning”
function significantly saves customers time and costs, as the SIL
safety function can be opened and confirmed remotely via the
SIMATIC PDM software. This eliminates the time required to travel
to the site and the steps required for local operation via local
pushbuttons and displays. Parameterization using the HART
communication protocol is very simple and fast because of the
innovative EDD description file integrated in the quick start
wizard. The transmitter can be connected to remote sealing
assemblies of various designs for special applications such as
highly viscous materials. The different models of the SITRANS
P320/P420 series pressure transmitters can be used to measure: -
Gauge pressure - Absolute pressure - Differential pressure - Liquid
level - Volumetric flow rate - Mass flow rate
