Analysis technology for industrial water monitoring

With CONDIX, the GHM GROUP presents a new, low-maintenance, quick-and-easy-to-install combination of measuring transducer and sensor, which saves times and money. The compact all-in-one solution for monitoring of conductivity in liquids requires neither a separate measuring transducer nor an expensive special cable or indicator and integrates directly into superordinate systems, such as SPS and SCADA, with the universal Modbus RTU interface. Intelligent functions for self-diagnosis also reduce maintenance costs and service work.

Less work saves more time per measuring point

The CONDIX digital conductive conductivity measuring transducer measures the conductivity of liquids by calculating the conductivity value based on the applied AC voltage, measured current and temperature. This value indicates the degree of contamination of the liquid. Operators of systems for fresh water monitoring and water preparation benefit from a durable and low-maintenance solution which also enables lower costs per measuring point thanks to reduced cable installation work. And, because the evaluation of the measuring result via the Modbus RTU digital interface takes place directly in an PLC or in the SCADA system, additional measuring transformers with display can also be eliminated. 

Easy to configure, maintain and operate

Since the sensor is integrated directly and digitally via the universal and easy-to-understand Modbus interface, all levels can be integrated into the superordinate system with a single bus cable. Significantly less cable is used than with conventional conductivity measurement, which drastically reduces the wiring and installation work. Installation takes place with standard fittings (PVC-U or PVDF) or by means of threaded connection and parameterisation takes place via PC tool prior to field installation. After installation, the Modbus interface enables comfortable configuration and calibration of the measuring transducer. Because the scaling and parameterisation are already stored in the CONDIX, any additional adaptation work in superordinate systems is eliminated. If it should be necessary to replace the CONDIX after years of service due to ageing, it can take place easily via 'Plug & Run'.

Predictive maintenance for minimal downtimes

CONDIX provides Industry 4.0 functions that are useful for intelligent self-diagnosis, efficient maintenance, reduced downtime and a longer sensor life. With integration of the transforming electronics and the implementation of a digital interface, the sensor provides information about its status, such as the internal sensor voltage and additional device parameters in addition to conductivity and temperature measuring variables. Technicians and operators can read the information and thereby ensure operation with minimal maintenance and interruptions, which maximises overall system availability. In addition, operating and communication status are recognisable at all times with the integrated status LEDs.

4-electrode measuring cell: resistant to polarisation effects

Because the digital, conductive conductivity measuring cell has a 4-electrode measuring cell, it covers an additional measuring range with only one measuring cell. In addition, with the four-pole technology, the power supply and measurement are separated, wherein the polarisation effects impairing the measurement also take place in the background.


With CONDIX, therefore, the GHM GROUP offers an extremely reliable and compact solution with an impressive price/performance ratio. This means added comfort and reduced costs for use in reverse osmosis systems, ion exchange systems, purest water, in salt water and underground water preparation on ships, in landfill seepage water and many additional areas of water analysis.
