Design and principle of operation

3 Design and principle of oper-
ation
The Media 7 device is a microprocessor-con-
trolled transmitter with dp cell for measuring,
indicating and transmitting the differential
pressure, pressure or measured variables de-
rived from them in stationary pressure ves-
sels and in transportation vehicles. The de-
vice is suitable for cryogenic gases, liquids,
gases and vapors. Measuring ranges be-
tween 0 to 160 mbar and 0 to 3600 mbar,
nominal pressure PN 60.
The device mainly consists of a dp cell (1),
housing with transmitter and a display (6).
The differential pressure ∆p = p
verted into an electric signal in the dp cell by
a sensor and processed in the microcontrol-
ler (2) which controls the display and D/A
converter of the two-wire version.
Four capacitive keys (4) are used to operate
the differential pressure meter and allow the
user to navigate within the menu on the dis-
play.
The modular design of the Media 7 device
allows it to be adapted to specific require-
ments. Optional additional functions are
available through the use of option modules
(see section 6.1).
A remote data transmission using the option-
al GSM module (9) is possible in the 24 V
version. Connection to the SAM TANK
MANAGEMENT web interface is established
over a mobile network (see section 6.2).

3.1 Configuration using the
The differential pressure meter can be con-
figured with SAMSON's TROVIS-VIEW Soft-
ware (version 4). For this purpose, the differ-
ential pressure meter has a digital interface
(SSP) to allow the USB port of a computer to
be connected to it using an adapter cable.
The TROVIS-VIEW software enables the user
to easily configure the differential pressure
meter as well as view process parameters
online.
