Memosens Technology and its Application in Industry


Introduction to Sensors

Sensor technology has been an important part of manufacturing industries for decades. For organizations in industries largely dealing with liquids such as petrochemical, oil and gas, and agriculture, sensor instruments are crucial to ensuring compliance with various standards and regulations.

Most importantly, sensors are essential in protecting the integrity of the final product, whether that final product is oil or orange juice.

Digital sensors as successors to analog sensors

 

A digital sensor is the modern version of analog sensor, where data conversion and data transmission are done digitally. It is only one part of a chain of measuring instruments that includes electronic and electrochemical sensors. This chain includes a cable, transmitter, and the sensor itself.

Traditional analog systems have the sensor converting the measuring parameter into an analog electrical signal. In digital sensors, the analog electrical signal is connected through a cable to a transmitter. The transmitter converts the electrical signal into a readable form such as a display, current outputs, or bus data transmission.

Liquid sensors and their drawbacks

Liquid sensors are suited to a wide range of applications in the process measurement, used across industries and locations. They are especially crucial in hygienic applications, wastewater treatment plants, and organizations in the chemical, oil and gas, and even automotive industries.

Liquid sensors are usually subject to massive demands on the transmission of the measured value from the sensor to the transmitter. For pH measurement, low measuring signals and very high sensor internal resistances necessitate a high-impedance connection to the transmitter. For this reason, conventional analog connector systems can provide the wrong measured value or even completely fail when moisture is present in the system.

Memosens Technology and its Benefits

Memosens sensors eliminate this issue that plagues old-fashioned, analog sensors. The revolutionary aspect of this technology is their capability to digitize the measure value in the sensor and send it to the transmitter without ever coming into contact with it.

The mechanically safe, non-contact connection between the sensor and the cable in Memosens sensors ensures that the technology will function properly, safely, and efficiently, even in underwater environments.  The connector is essentially corrosion-free, eliminating the risk of leaks or measured value distortion caused by moisture, or even corrosion due to salt bridges.

Memosens systems boast galvanic separation between the medium and the transmitter, which operates independently of symmetrically high-resistance, asymmetrical, or impedance converters. The sensor is easily replaced with calibrated sensors. This guarantees user-friendly, plug-and-play operation with automatic sensor recognition.

All sensor-related data is stored directly in the sensor head. This allows operators to perform predictive maintenance, which significantly reduces maintenance costs and increases sensor operating time.

Memosens Technology in Endress+Hauser’s Liquiline CM14

Memosens technology is a crucial component in Endress+Hauser’s Liquiline CM14, a 4-wire transmitter with a compact design for mounting in control panels or cabinets. A pH/Redox, conductivity or oxygen sensor can be connected to the CM14, which receives the measured values digitally via Memosens technology.
