Endress+Hauser introduces Memobase

August 2008 IT in Manufacturing

Endress+Hauser has announced the launch of Memobase in South Africa, a software package that allows central data and sensor management in the laboratory. The software has been developed for use with Memosens sensors, and delivers higher product quality and reduces maintenance costs.

Memosens, coupled with the Liquiline transmitter, is the basis of deployment for the technology. This sensor technology enables data storage and digitalisation of the analog measuring signal directly in the sensor. The digital data packages comprise of the actual process values, including temperature. They also include calibration data, adjustment data and process-related data, such as total operating hours and operating times under extreme process conditions. This means that Memosens sensors can be calibrated, adjusted, regenerated and cleaned centrally in a laboratory and not directly at the measuring point. All that needs to be done with Memosens is to replace the sensors onsite with calibrated sensors.

“The reproducible laboratory conditions enable a more precise calibration and therefore more accurate process management,” explains Dr Monika Heisterkamp, head of product management at Endress+Hauser Conducta.

In addition, regular regeneration and cleaning prolongs the service life, particularly of the pH sensors, by up to 40%. This concept reduces process downtime and results in longer calibration intervals due to optimised sensor maintenance. Further cost savings are achieved by virtue of the fact that the sensors can be replaced by operating staff who do not require any specialised knowledge of measurement technology.

Combined with the characteristics of Memosens technology already mentioned, Memobase supports predictive maintenance of sensors. “Efficient data and sensor management using Memobase is an essential component of the new maintenance strategies of our customers,” says Heisterkamp.

Memobase has already been put to the test across all industries. “Here, predictive maintenance results in cost savings thanks to improved asset management. This mainly involves more accurate process control due to more precise calibration, in addition to cost reductions stemming from reduced sensor usage and more efficient staff planning.”

While the sensors are calibrated centrally in a laboratory, data is recorded automatically and efficiently. Memobase consistently records all data specific to each measuring point, including calibration/adjustment data as well as process data. In this way, the complete life cycle of the sensor is documented, from commissioning to scrapping. Using this data, measuring systems and maintenance concepts can be analysed and, if necessary, optimised. It is also possible to study the complete history of the measuring point. For the purpose of evaluation in Excel or SAP, the data can also be exported.

Convenient data and sensor management with Memobase CYZ41D is available immediately for Memosens pH sensors. Sensors with Memosens technology are currently available for the parameters pH (glass and ISFET), ORP, dissolved oxygen and conductivity. Memosens sensors will soon be available for chlorine measurement technology.
