Intended use
The Media 7 Differential Pressure Meter is a microprocessor-controlled transmitter with dp
cell for measuring, indicating and transmitting the differential pressure, pressure or measured
variables derived from them. The device is suitable for cryogenic gases, liquids, gases and
vapors. The device is designed to operate under exactly defined conditions (e.g. operating
pressure, process medium, temperature). Therefore, operators must ensure that the device is
only used in operating conditions that meet the specifications used for sizing the device at the
ordering stage.
The Media 7 device can be operated in hazardous areas in Zone 1 or higher only. The
measurement of flammable or explosive media is only permitted with the following
approvals:
− Type 5007-1-120x (ATEX): II 1/2G Ex ia IIB T4 Ga/Gb
− Type 5007-1-121x (IECEx): Ex ia IIB T4 Ga/Gb (IECEx)

vice for its intended purpose or for damage caused by external forces or any other external
factors.
Î Refer to the technical data for limits and fields of application as well as possible uses.
Reasonably foreseeable misuse
The Media 7 Differential Pressure Meter is not suitable for the following applications:
− Use outside the limits defined during sizing and by the technical data
Furthermore, the following activities do not comply with the intended use:
− Use of non-original spare parts
− Performing maintenance activities not specified by SAMSON
