Sensor device for measuring the level of material contained in a container

A set comprising:

• a connector configured to be secured to a wall of a sealed enclosure of a container;
• and
• a sensor device configured to measure a level of material in the container including the sealed enclosure configured to contain material defining a free surface inside the enclosure, the sensor device comprising:
• a shell including a measurement window,
• at least one contactless level sensor housed inside the shell, the at least one contactless level sensor comprising
• an emitter configured to emit a detection signal, and
• a receiver configured to receive a reflected detection signal comprising the detection signal after reflection,
• the measurement window of the shell enabling passage of the detection signal emitted by said emitter from the inside of the shell to the inside of the enclosure of the container and the passage of the reflected detection signal, after reflection against the free surface of the material inside the enclosure of the container, from the inside of the enclosure of the container towards said receiver inside the shell, and
• a fastener secured to the shell, the fastener being configured to enable the removable fastening of the sensor device, outside the enclosure of the container, on a connector secured to a wall of the enclosure of the container, with the measurement window of the shell positioned opposite a corresponding opening formed in the wall of the enclosure of the container,
• the at least one contactless level sensor being configured to emit a measurement signal relating to the level of the material inside the enclosure of the container as a function of the reflected detection signal received by the receiver;
• and
• wherein the connector has a through hole configured to be positioned opposite and in line with an opening formed in said wall of the enclosure of the container, and
• wherein the sensor device is configured to be removably fastened on the connector via the fastener with the measurement window of the shell opposite and in line with the through hole of the connector and the opening formed in the wall of the enclosure of the container, said through hole being configured to be crossed by the detection signal emitted by the emitter and by the reflected detection signal intended to be received by the receiver.
