Digital integration makes pH and ORP measuring points easier to commission, monitor and maintain. PHIX screws directly onto combined electrodes with S7/S8 or VarioPin connection head and provides pH or ORP values via RS485 with Modbus RTU protocol.
The converter reduces cabling effort by using standard electrode heads instead of complex special cables. It records process values, identification data and diagnostic data, including process temperature with integrated Pt1000, glass impedance, internal temperature and system power. Glass impedance helps indicate contamination, short circuit, breakage or the presence of the sensor chain.
Maintenance becomes more transparent through guided 1- or 2-point calibration, manual input of zero point and slope, and storage of up to 5 calibration results with timestamps. Operating hours and temperature- and pH-related operating times support sensor stress evaluation, while SENSware and MULTICON enable parameterization and calibration.
PHIX is available for combined electrodes with S7/S8 plug or VarioPin (VP) plug connection heads.
The converter records pH or ORP as the main value and can also record process temperature with electrodes that include Pt1000.
Guided 1-point and 2-point calibration routines are available, with manual entry of zero point and slope.
The device records total operating time as well as temperature- and pH-related operating times.
The interface uses RS485, Half-Duplex with Modbus RTU protocol and selectable baud rates from 1200 to 19200.
Optical signaling shows supply voltage, bus communication and addressing status through LEDs.
Configuration and calibration are carried out via SENSware, MULTICON-H or Modbus RTU.
The PVC-U housing with PMMA window uses an 8-pole round plug and has ingress protection IP67.
