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 Modbus® communication capabilities via the seperate
RS485 wires where both the primary measuring signal (pH or redox) and the
secondary measurement signal can be read. Modbus® communication gives
the possibility to configure nearly all parameters like measuring ranges,
electrode parameters and also commands for buffer adjustment.
Modbus® communication requires that pHix® Compact is connected to a
RS485 Communication device or a PLC with RS485 interface.
pHix® Compact is delivered as standard for pH or redox (ORP) measurement
and temperature, but can also be delivered with non-standard settings.
