● For pH and Redox single-rod measurement chains with VarioPin or S7/S8 connection head
● Guided 1- or 2-point calibration procedure ● Glass impedance measurement for sensor condition detection
● Elimination of expensive special cables and high signal quality through sensor digitization
● Provides process values, identification data, diagnostic data ● Configurable calibration timer
● Stores up to 5 calibration results with timestamps ● Records operating hours as well as temperature and pH-related
usage times (sensor stress)
Characteristics The digital converter PHIX is used for the potentiometric measurement of the pH or ORP value of a single-rod measuring chain.
For this purpose, the transmitter is screwed onto a VarioPin or S7/S8 standard connection head, eliminating the need for complex special
cables.
The Modbus RTU protocol on RS485 is used for communication. This enables integration into existing networks as well as use with the
multi-channel controller MULTICON.
The logging function can be used to evaluate the timing, slope and zero point of the last 5 calibrations. The integrated operating hours
counter records the operating time as well as temperature and pHrelated operating times. These are indicators of sensor stress and allow conclusions to be drawn about the intended use of the measurement chain.
Calibration can be carried out via a guided 1- or 2-point calibration as
well as by manual input of zero point and steepness.
In addition to the main measured value, PHIX records the process temperature (measuring chains with integrated Pt1000), the glass
impedance, as well as internal temperature and system power.
The glass impedance is an indicator of contamination, short circuit, breakage or the presence of the sensor chain itself. Internal temperature and supply voltage allow additional conclusions to be drawn
about the intended use of the measuring point.
Parameterization and calibration can be carried out via the configuration tool GHMware as well as via the multi-channel controller
MULTICON.
GHMware enables the calibration of PHIX and a single-rod measurement chain in the laboratory. In combination with automatic addressing, maintenance can be carried out "Plug & Measure".
