A combination-measuring transducer to monitor the conductivity of liquids is now available.
Conductivity of water measures the water’s ability to pass electrical flow. This function is important to industries such as brewing, pharmaceutical industries and food manufacturing processes. The transducer technology can also be used in the monitoring of water preparation, reverse osmosis and ion exchanger systems in salt water, underground water preparation on ships, gas scrubbers and landfill seepage water.
This Martens CONDIX all-in-one transducer does not require a separate measuring transducer or a special cable or indicator. It integrates directly into superordinate systems such as SAPS and supervisory control and data acquisition with the universal Modbus remote terminal unit interface.
The measured ohmic resistance provides information about the ion concentration in the electrolyte. The integrated transducer then converts the signal into a digital process value and further scaling in the subordinate system is not required.
The universal Modbus interface enables configuration and calibration of the measuring transducers. Standard fittings are used and parameterisation prior to field installation can be carried out using a personal computer.
GHM Messtechnik South Africa are the local distributors of the system for the GHM Group.
The company states that the transducer provides Industry 4.0 functions that can be used for self-diagnosis, maintenance, potentially reducing downtime and increasing sensor life. With the 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.
- Compact design
- The measuring transducer is integrated in the sensor and has a direct connection to the SPS
- Less cabling facilitates easier installation
- All levels up to the PLC can be connected with one bus cable
- Universal Modbus interface enables convenient configuration and calibration of the measurement transducer
- Four-electrode measuring cells means resistance to polarisation effects
- Predictable maintenance can potentially reduce downtimes
