Whether corrosive chemicals, heat or impossible to access application areas: sensors from Endress+Hauser are known for withstanding many extremes. However, those ambient conditions are an unfavourable calibration environment for the sensors. Would it not be better to calibrate all sensors from the process conveniently in the lab under constant conditions and retrieve all calibration values, measuring values and sensor information without any effort, simply by clicking a mouse? Thanks to Memobase Plus and inductive Memosens sensors, the future has arrived – for up to four sensors simultaneously.
Memosens and Memobase Plus – the complete package
Memosens is based on non-contact data transmission between sensor and cable that makes the system absolutely robust against external influences such as moisture, corrosion and salt bridges. Unpleasant surprises from measuring point failures caused by these factors are a thing of the past and maintenance work such as calibration and sensor replacement can be planned in advance.
Moreover, sensors with digital Memosens technology are intelligent. In addition to calibration data, they save information such as operating hours under various conditions and the tag name. As a result, their use is not tied to a specific transmitter.
Sensors can be calibrated under optimal conditions in the lab and all associated data is stored in a database. Reports are created simply by clicking a button. These options are unheard of for calibration on a process transmitter or would involve time-consuming and error-prone work by hand.
The Memosens package is rounded out by pH buffers manufactured in a buffer lab accredited by German agency DaKKs and by Memocheck products. These Memocheck products can simulate Memosens sensors (choice of measuring values, calibration and status) and thus make an essential contribution to simple validation of the measuring point and to troubleshooting.
Memobase Plus consists of a software program with a database and corresponding interfaces, which can be used to connect the sensors directly to any standard PC via USB, turning the computer into a calibration and measuring station. Sensors for the parameters of pH/ORP, dissolved oxygen (amperometric), conductive and toroidal conductivity and chlorine can be operated in any desired combination. The individual tasks can be freely chosen: calibrate four sensors at the same time or calibrate one sensor while a second is measuring and a tag is written to the third – anything is possible.
Memobase Plus is based on the plug-and-play concept that has already brought success to the Liquiline transmitter platform. The software identifies the digital Memosens sensors automatically and offers the right functions for the sensor. The program is simple and easy-to-understand, sorted by the work tasks of measurement, calibration, reports and sensor management. The intuitive operation and self-explanatory system, which also provides many helpful resources and instructions, allows every user to master the program after just a short time. This prevents operator errors from the beginning.
Reaching savings goals quickly
Memobase Plus operates up to four sensors simultaneously in any combination. This speeds up measurement and calibration of all Memosens sensors with an inductive plug-in head and ultimately saves time and money. For each user, there is the right package at the right price. Memobase Plus consists of basic software with available upgrades. Even ‘MemoLink’ sensor connection boxes, and thus the means of determining the number of channels, are available individually and can be retrofitted at any time. The system also saves work space in the calibration laboratory Users only need one interface for all types of sensors, no bulky transmitters and software for measuring, calibration and documentation. And finally, continuous savings on personnel costs, since analysis specialists only have to calibrate, while sensor replacement – which also had to be done by specialists – can now be done by non-specialist staff in a few minutes. Maximised availability of measuring points is a free extra.
Calibrate reliably and attain high quality
Memobase Plus actively provides reliable and error-free work. Because the sensors are calibrated in a laboratory, calibration is always performed under optimal conditions – a critical factor for its accuracy and thus for the quality of measurements as well. The user administration also provides security and, with the configurable password specifications, adapts to the requirements of a company and pertinent standards and regulations. In addition, the lab environment is much safer for workers. In the process environment, where workers are often exposed to heat or cold, dirt and vapours, the required work steps have been minimised to replacing the sensor.
Work in compliance with FDA CFR 21 Part 11 and be prepared for audits
With complete automation, the program creates data records of operating conditions, measurements and calibrations and documents all of the associated information. This ensures seamless traceability and audits are prepared quickly and easily. Reports can be created in pdf form at the click of a button. The data records can also be exported as CSV files and reused, without paperwork, for optimisation and analysis in Excel, for example. In addition, higher-order systems such as LIMS can access the CSV files.
All of the information is stored in a local or central database which, thanks to a checksum, reveals any tampering and labels it in a manner that is impossible to overlook. The central database also enables multiple persons to have access at different locations, optimising the flow of information and making work more efficient.
Automated ‘as found – as left’ deviation monitoring
How was the measurement quality of the sensor immediately before calibration and, in comparison, what was it like immediately after calibration? With the automated ‘as found – as left’ measurement, this can be carried out easily and documented as an optional part of all calibration procedures. Based on the identified delta values, differences in measured values before and after a calibration can be explained and the application-related sensor load can be better estimated and tracked.
First-time reproducibility of laboratory and process values
For the first time, the same calculation, cables and sensors as those in the process are used in the lab with Memobase Plus. This makes the measuring values genuinely comparable, since differences due to the measuring system are eliminated. Therefore, up-scaling is also easier than ever: the sensors in the process are guaranteed to measure identically to those in the test system. With automatic temperature and medium compensation, the only explanation for different results can be the medium’s reaction with air. The sensors can be validated at an early stage and accompany the product development process from the beginning – with consistent results from start to finish.
This allows Memobase Plus to centralise maintenance of Memosens analytical sensors, thus making it more efficient while giving users improved calibration quality and automated documentation that leaves nothing to be desired.
