While digital technology has become prevalent in many areas of process automation, it has not been applied to pH measurement to date. Trendsetter, Endress+Hauser, believes it has changed that by introducing the first ever pH measurement digital sensor.
The MemoSens sensor family for pH measurement comes with electronics integrated in the sensor. This permits the storage of important calibration and sensor identification data to be stored right where it is needed - in the sensor. It also enables the easy transfer of data to external storage media and evaluation programs, which gives the user an accessible source of up-to-date information for documentation of sensor history, as well as the determination of maintenance intervals or for preventative maintenance.
Handling is simplified due to integrated calibration data for sensor pre-calibration independent of the actual measuring point. This means that field calibration will become a thing of the past, as the pH sensors can be conveniently calibrated in the laboratory. Accuracy of calibration is higher because there are no external influences such as wind and weather that can affect the quality. It is also no longer necessary to install the transmitter close to the sensor; it can be positioned in the control room - also reducing cabling and mounting material overhead.
A contactless connector system (believed to be the only one in the entire analysis market) is offered with the new MemoSens sensor family. This provides for reliable measurement with increased availability due to digitisation of the measured value in the sensor and data transfer via a countactless plug-in connection. Digital transfer also results in speedy alarm signalling in the event of sensor failure or if the connection between the sensor and transmitter is interrupted. The non-contacting coupling between the sensor and cable eliminates some basic problems caused by moisture such as loss of high impedance through contact corrosion, while also providing electrical isolation of the transmitter from the medium. At the same time it permits the use of digital signals in hazardous locations.
It is envisaged that the time consuming start-up and maintenance of the measuring point in the field will be done away with in favour of sensor replacement in the future. This will result in a substantial increase in measurement availability, optimised signal quality and a reduced workload for the service personnel.
