Construction
pHix® Compact is a loop powered 4-20 mA 4-wire transmitter with power supply and
measuring signal transmitted over the same pair of 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 also gives the possibility to
configure nearly all parameters like measuring ranges, electrode parameters and also
buffer settings for buffer adjustment.
Modbus® communication requires that pHix® Compact is connected to a RS485
Communication device or a PLC with RS485 interface. The pH loop must be applied with
10-28VDC supply.
pHix® Compact is delivered as standard for pH or redox (ORP) measurement and
temperature, but can also be delivered with non-standard cable length.
