Abstract
An optochemical sensor for determining a measurement signal, which correlates with a concentration of an analyte of a measuring fluid, comprises: a sensor cap including a sensor spot, wherein the sensor spot contains at least one analyte-sensitive indicator dye and a state description indicator which reflects the aging state of the sensor spot; a radiation source to radiate excitation radiation onto the sensor spot and to excite a luminescence of the indicator dye; a radiation receiver to receive reception radiation emitted by the sensor spot; and a sensor circuit electrically connected to the radiation source and the radiation receiver and configured to control the radiation source and to generate, based on an intensity of luminescence and/or a phase angle of luminescence, a measurement signal representing the concentration of the analyte in the measuring fluid in contact with the sensor spot.
