    Patent number: 10876968
    Abstract: An sensor (2) based on an optical-sensing technique measures gaseous or dissolved analytes in a measurement medium (4). The sensor has a sensor housing (6) and an optochemical sensor element (20, 220) arranged within the sensor housing. The optochemical sensor element (220) has a substrate (222), a sensing layer (224) and a barrier layer (230). The barrier layer is arranged to protect the optochemical sensor element from interfering substances (234) present in the measurement medium.
