Measurement instrumentation, services and solutions company Endress+Hauser launched Memosens 2.0 digital technology last month, which provides simple, safe and connected liquid analysis.

Process plants typically use a multitude of sensors, each of which is normally connected to a transmitter. Older sensor technologies use analog signals to communicate with transmitters, but more modern models employ digital technology to improve accuracy, ease calibration, simplify troubleshooting and reduce required maintenance.

Memosens technology converts the measured value to a digital signal and transfers it inductively to the transmitter, offering safe data transfer for increased availability of the measuring point and trouble-free operation. With Memosens 2.0, liquid analysis measuring points now become completely future-proofed and ready for Industrial Internet of Things (IIoT). This new technology is available for pH/oxidation/reduction potential conductivity, and dissolved oxygen sensors and it will be extended to the complete sensor portfolio for liquid analysis.

Memosens 2.0 sensors store numerous relevant data points, such as operating hours, minimum and maximum temperatures, measured values, calibration histories and load matrices. All this data can be used and processed for comprehensive analysis and more precise process management. The sensors also provide a sound basis for predictive maintenance strategies when used in conjunction with Endress+Hauser’s Heartbeat Technology, along with enhanced IIoT services with the Netilion ecosystem.

Memosens 2.0 combines cutting-edge technology with maximum practicability. The Memosens sensors are equipped with highly integrated electronics, they can be calibrated and adjusted under lab conditions that are favourable for the operator, and stable for precise results. Replacing sensors in the field is a simple process and can be performed in a timely manner thanks to the lockable bayonet connector and automatic sensor identification by the transmitter.

Non-contact digital data transmission eliminates the effects of moisture, corrosion and salt bridges – with alert messaging if the signal transmission is disturbed by other factors. Galvanic isolation ensures accurate measurement in the presence of electromagnetic interference and other electrical noise.

Memobase Plus software provides full traceability of all sensors used, supporting operation according to the strict guidelines applicable to various regulated industries. Memosens 2.0 offers error-free flexibility for measuring points in hazardous areas because all explosion-proof sensors can be connected to all Endress+Hauser transmitters with the same ratings.
