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 differential pressure meter must only be operated in hazardous areas in Zone 1 or high -
er. 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)
