Service .book Page 35 Wednesday, February 1, 2012 11:58 AM SERVICE 6 OPTISENS CL 1100 6.1 Maintenance 6.1.1 Cleaning The sensor can be equipped with the patented automatic sensor cleaning (ASR, patent Dr. A. Kuntze). An electrochemical process causes outgassing on the measuring electrodes, which can dissolve even tough coatings such as lime deposits or grease. The ASR considerably increases the maintenance interval of the sensor.
.book Page 36 Wednesday, February 1, 2012 11:58 AM 6 SERVICE OPTISENS CL 1100 6.1.2 Aging and re-calibration CAUTION! The life time expectation of the sensor depends on the application. Normally, the life time lies between 2 and 4 years. In applications with high reliability requirements, e.g. drinking water, we recommend replacing the sensor once a year. The sensor has to be re-calibrated in regular intervals due to aging effects of the reference electrode.
