A liquid level sensing device (10) comprises an electrically non-conductive member (12) having an outer surface and having a distal portion (18) for immersion in liquid. Two electrically conductive elements (26, 28) are positioned in spaced relationship with respect to each other on the outer surface of the member (12) on the distal portion (18) thereof. Each of the conductive elements (26, 28) are connectable to an electrical circuit so that an electrical signal is detectable when both of the conductive elements (26, 28) contact the liquid into which the distal portion (18) of the member (12) is immersed. In this fashion, the level of liquid in a container or well may be sensed. |
