In today’s industries, accurate and reliable analytical process measurements are crucial for plant safety and product quality. Endress and Hauser 's Memosens technology has revolutionised the reliability of data transmission and is fast becoming the de-facto analytical measurement technology.
Analytical measuring systems that use analogue connections between sensor and transmitter face a range of technical problems. For instance, pH electrodes generate very weak electric currents that can easily be rendered inaccurate and unreliable due to poor connections between the electrode and sensor cable. Measurements are also affected negatively by poor quality or aged cabling between the electrode and transmitter, and external environmental influences like moisture and temperature changes.
In order to overcome operational problems associated with analogue pH measurements, Endress and Hauser’s developed Memosens digital technology, specifically to assure interference-free, reliable data transmission of up to 100 metres between transmitter and electrode. Whilst Memosens started by solving the problems specific to pH measurements, the additional benefits that it offered were so revolutionary that it has been implemented across ORP, conductivity, turbidity, nitrates, dissolved oxygen and more.
The plug-and-play capabilities of Memosens technology allows for fast commissioning, calibration and maintenance while the data storage capability means sensors can be precisely pre-calibrated in a workshop or laboratory and stored ready for use for up to one year. This provides a safe and controlled environment for the personnel undertaking the calibrations or maintenance.
Memosens technology is available for a range of parameters, making it suitable for a wide range of applications in food, beverage, pharmaceutical, water, wastewater and mining industries.
