Abstract:
1. A device for controlling a condensate lift pump, comprising a means for detecting at least two condensate levels in a container, and a means for activating and for stopping said pump according to said levels, in which said detection means comprises a capacitive detector comprising at least three electrodes (GE, RE, EOFF, EON, EAL), each comprising a conductive armature isolated by at least one dielectric isolation element, connected to a means for processing: a ground electrode (GE); a first level detection electrode (EOFF); and a second level detection electrode (EON), wherein said processing means comprises a means for measuring a first capacitance (C wherein the lengths of said first level detection electrode (EOFF) and second level detection electrode (EON) are defined so as to come into contact with said condensates, when the latter respectively reach said first level and said second level in said container, and wherein the electrodes are produced on distinct supports not having a submergible physical continuity between them.
