Differential Pressure (± 2 Mpa (20 Bar)) - Dräger P7-TDX Instruction Manual

Instruction Manual Dräger P7-TDX
7.5 Differential pressure (± 2 MPa (20 bar))
You use 2 external high pressure sensors for the differential pressure measurement
(± 2 MPa (20 bar)) and connect them to 2 of the connections for digital sensors. The ex-
ternal high pressure sensors must have the same measuring range.
The "zero" function sets the indicated differential pressure to zero; this means that the sig-
nals of both the high pressure sensors are equalized.
After the differential pressure measurement is started, the
starting differential pressure, the starting pressure, the actual
pressure as well as the differential pressure and the duration
of the measurement are shown.
The displayed differential pressure is the difference between
the external pressure sensor is plugged in first and the exter-
nal sensor that is plugged in second, e. g. DS1 minus DS2.
