Construction
pHix® Compact is a loop powered 4-20 mA 2-wire transmitter with power
supply and measuring signal transmitted over the same two wires.
pHix® Compact also has HART® communication capabilities via the mA wires
where both the primary measuring signal (pH or redox) and the secondary
measurement signal can be read. HART® communication gives the possibility
to configure nearly all parameters like measuring ranges, alarm limits, electrode
parameters and also commands for buffer adjustment.
HART® communication requires that pHix® Compact is connected to a HART®
communicator or a PLC with HART® interface.
pHix® Compact is delivered as standard for pH or redox measurement, but can
also be delivered for other types of measurement and non-standard settings.
