A method for manufacturing an inductive conductivity sensor, with coils on both sides of a circuit board are placed surrounding an opening of the circuit board. The circuit board with the coils is inserted into a housing, wherein a sleeve is inserted in the housing through a second opening of the housing through the opening of the circuit board out to a first opening. The first opening, the second opening and the opening of the circuit board are aligned with one another, wherein the sleeve includes a first end section and a second end section and the sleeve is inserted with the first end section first in the housing, and wherein the sleeve is welded with the housing by means of a sonotrode by ultrasonic welding. The first end section of the sleeve is welded with the housing and with a counterpart inserted into the first opening. The invention relates further to an inductive conductivity sensor. |
