Capacitive liquid level sensor and liquid sensor assembly

A capacitive liquid level sensor, the sensor comprising:

• a sensor body in the form a tongue with a freely depending portion extending to a distal tip at, in use, its lowermost end;
• a set of spaced capacitive electrodes extending along the tongue towards the distal tip, wherein, in use, when the distal tip of the tongue is immersed in a body of liquid, the capacitance between the electrodes changes depending on the depth of the body of liquid;
• wherein the width of the tongue increases in the direction towards the distal tip thereby defining a widest part of the freely depending portion of the tongue at least for part of the bottom half of the freely depending part of the tongue;
• and
• wherein the electrodes terminate short of the widest part of the freely depending portion of the tongue.
