When it was introduced to the market 17 years ago, Memosens technology revolutionised liquid analysis. By converting the measured value to a digital signal and transferring it without interference to the transmitter, Memosens eliminated the problems associated with moisture and made it possible to calibrate sensors in the lab. Now Memosens 2.0 is future-proofing measuring points and preparing them for IIoT.
The first generation of Memosens enabled data such as the sensor’s time in use or environmental influences to be stored directly in the sensor head, meaning calibration or adjustments could be carried out in an optimal laboratory environment rather than in the field. With Memosens 2.0, this data will now be combined with the possibilities afforded by the Industrial Internet of Things (IIoT). The sensor data can be analysed and interpreted using Endress+Hauser’s Netilion IIoT ecosystem to obtain information and recommendations related to maintenance, servicing and process optimisation.
Determining sensor health
Memosens sensors offer significantly more data for determining the health of the sensor, such as the history of the last eight calibrations or adjustments. A new feature of the second generation is direct analysis of the sensor state, which includes measurement data such as time, pH value and temperature. This information is directly related to the health of the sensor.
The transmitters have also been impacted by digitalisation. Today, Memosens sensors are operated by transmitters such as the two-wire Liquiline CM42 or the four-wire Liquiline CM44x, which enable genuine plug & play capability. There are also new compact transmitters such as the Liquiline CM82, which can be simply operated via Bluetooth. With the introduction of Heartbeat Technology in the Liquiline CM44x, users can more easily determine the current condition of a sensor. By glancing at the display, they can tell if the sensor is working properly, whether maintenance is required or if the sensor needs to be replaced. Heartbeat Technology uses the data stored in the Memosens sensor head, such as pH slope, zero point and length of operation at high temperatures, to provide information on sensor health.
Another key step on the path to digitalisation is Memobase software, which makes calibration and adjustment possible in the lab without additional equipment; all that’s required is a laptop. In this environment you can analyse the sensor’s entire life cycle and predict calibration cycles and life span.
Using data
Data-driven decision making takes process control to the next level in terms of safety and efficiency. One of the big challenges in the digital transformation of the process industry is making the data available in the cloud and scaling the digital solutions to the entire plant. The new generation of Memosens sensors, in combination with the Netilion platform, offers a solution. The diagnostic functionality of Memosens sensors enables data-driven decisions, leading to optimised maintenance and calibration cycles and, as a result, more efficient production.
