Introduction
GB pHix Compact Manual 100318
Construction
pHix
® Compact is a 4-20 mA 2-wire trans-
mitter with power supply and measuring
signal transmitted over the same two wires.
pHix
® Compact also has HART ® communi-
cation capabilities via the mA wires where
both the primary measuring signal (pH or re-
dox) and the secondary measurement signal
can be read. HART
® communication gives
the possibility to configure nearly all para-
meters like measuring ranges, alarm limits,
electrode parameters and also commands
for buffer adjustment.
HART
® communication requires that pHix ®
Compact is connected to a HART ® commu-
nicator or a PLC with HART ® interface.
pHix ® Compact is delivered as standard for
pH or redox masurement, but can also be
delivered for other types of measurement
and non-standard settings.
An identical marking is found on the pH
transmitter cable:
