Siemens 7MF0300/7MF0400 Series Gauge Pressure Transmitters

SITRANS P320/P420 pressure transmitters are digital pressuretransmitters featuring extensive user-friendliness and  high accuracy, The parameter assignment is performed using input buttons or the HART interface.

The comprehensive functionality makes for precise adjustmentof the pressure transmitter to the requirements of the  plant. Operation is very user-friendly in spite of the numerous setting options.

Due to their advanced diagnostic functionalities according to NAMUR NE107, the SITRANS P320/P420 pressure  transmittersare very suitable for use in chemical plants. Thanks to the advanced diagnostic functions and the process  value storage, the SITRANS P420 is "Ready for Digitalization".

The "Remote Safety Handling' function saves customers signifi-cant amounts of time and money, because the SIL function  can be switched on and validated remotely via SIMATIC PDM, This eliminates travel times and on-site operation via the  local displayor keyboard.

Parameter assignment using the HART protocol is very easy andquick thanks to the innovative EDD with integrated Quick  Startwizard.

The transmitters can be equipped with various types of remoteseals for special applications such as the measurement of  highlyviscous substances.

SITRANS P320/P420 pressure transmitters are available in vari-ous versions for measuring:

· Gauge pressure

· Absolute pressure

· Differential pressure

· Level

· Volume flow

· Mass flow
