The advantage of Memosens technology is that digitised measured values and sensor information are transmitted via a non-contact connection from the sensor to the cable, and as a digital signal to the transmitter. Selecting the components for a measuring point is easy, as Liquiline transmitters automatically recognise the connected sensor type. It is not necessary to select a parameter-specific transmitter. The sensors are also easy to handle when it comes to calibration, and thanks to Memosens technology, field calibration is no longer necessary. Sensors can be easily and safely calibrated in the laboratory or in the factory. This is possible as the relevant data is stored in the sensor head electronics.
Pre-calibrated plug-and-play sensors complement a full range of parameters. In summary, the operation of these Memosens sensors is straightforward, cost effective and designed to support quick commissioning and easy maintenance.
Ultimate reliability in production and maintenance
Non-contact signal transmission makes Memosens sensors very reliable, as problems do not arise due to moisture and EMC thanks to the inductive, digital signal transfer. Furthermore, disruptions to the connection between sensor and transmitter are displayed actively, so errors can be eliminated immediately, thereby increasing process safety. This technology also increases operational safety for personnel considerably. Since the sensors can be exchanged quickly, Memosens can significantly help to reduce the time that maintenance staff spend in dangerous environments.
Heartbeat technology determines the sensor status for pH and oxygen sensors
Heartbeat technology’s ‘sensor status’ functionality was adapted in the new pH sensors. The sensor load function enables a detailed analysis of the current condition of the sensor. In addition to other parameters, the sensor diagnosis considers the measured pH values, the temperatures the sensor was exposed to and the time factor. The result is a reliable assessment of the sensor condition, making it easier for plant owners to plan maintenance work right up to sensor replacement if necessary.
Heartbeat technology also offers a significant improvement in the case of amperometric oxygen sensors. The new oxygen sensors now feature an electrolyte counter, which provides accurate information on the condition of the electrolyte and informs the user about upcoming maintenance requirements in a timely manner.
Tools for easy maintenance and repair
Even without the implementation of Industry 4.0 or IIoT technology, Endress+Hauser offers numerous online tools to help possible maintenance and repair procedures. For example, the Endress+Hauser Operations app for smartphones and tablets can be used for unique identification of a Memosens 2.0 sensor either by reading the DataMatrix code (DMC) lasered onto the sensor, or entering the serial number manually. The app can then provide the user with immediate information about the sensor on site in the form of documentation and maintenance instructions, or information on required spare parts. The production date, detailed order code and product-specific certificates are also displayed. This information makes onsite maintenance work easier and leads to a successful outcome faster.
Easy to use in hazardous areas
The new Memosens generation also makes instrumentation in hazardous areas easier. Previously approval was system-based, comprising the CYK10 cable and the individual sensors listed in the approval. Expanding the sensor portfolio was always complicated at this point. Now, all the components have an individual approval, and the measuring point can be easily and safely configured, calculated and installed based on the corresponding connection characteristic data. This also applies to use in hazardous areas. The onsite installation does not need to be changed. Sensors from both the first and new generation can be connected and operated with the CYK10 cable. This protects the investment made by users of first generation Memosens technology.
Futureproof your liquid analysis with Memosens 2.0
The first generation of Memosens technology is widely used for liquid analysis in many different industries thanks to its simplicity, reliability and safety. Memosens 2.0 is now the next logical step in its evolution towards connectivity and Industry 4.0. The sensors themselves are smart, for example, they can communicate digitally and carry out a self-diagnosis depending on the measuring parameter. It is now also possible to integrate them in cloud solutions such as Endress+Hauser’s Netilion IIoT ecosystem, so that the sensor data can be used for more in-depth analyses and are ready for the future.
