Optical sensor, especially for determining substance concentrations in aqueous solutions by means of a fluorescence measurement
First Claim
1. A method for determining substance concentrations in aqueous solutions by means of a fluorescence measurement with an optical sensor, the sensor comprising:
- a housing;
sensor electronics;
an optical transmitter;
an optical receiver; and
a sensor head, which contains a sensitive element and which is adjoined by said housing, said housing containing said sensor electronics; and
wherein said sensor head and said housing are separable, wherein different sensor heads having different sensitive elements are connectable to said housing containing said sensor electronics;
the method comprising the steps of;
irradiating said sensitive element with light from said optical transmitter, wherein said sensor electronics excites said optical transmitter;
radiating back a light characteristic by said sensitive element;
detecting said back-radiated light characteristic by said optical receiver;
forwarding said back-radiated light characteristic from said optical receiver to said sensor electronics;
evaluating said back-radiated light characteristic by said sensor electronics, wherein said light characteristics are generated by said different sensitive elements; and
recognizing said sensitive element in said sensor head automatically by said sensor electronics by comparing said back-radiated light characteristic with stored measurement data and/or characteristic lines for recognizing said sensitive element.

Abstract
An optical sensor, comprising a sensor head, which contains a sensitive element and which is adjoined by a housing, which contains sensor electronics, wherein the sensitive element is irradiated with light from an optical transmitter and a light characteristic radiated back by the sensitive element is detected by an optical receiver and evaluated by the sensor electronics. The sensor head and the housing are embodied to be separable, wherein different sensor heads having different sensitive elements are connectable to the housing containing the sensor electronics and the sensor electronics evaluates the light characteristics generated by the different sensitive elements.
