Abstract

See full text

A liquid level sensor comprises a main body, a common electrical contact, a base-level electrical contact, and a first-raised-level electrical contact. The common electrical contact and the base-level electrical contact together define a base liquid sensing level. The common electrical contact and the first-raised-level electrical contact together define a first raised liquid sensing level. Electronic circuitry is responsive to a path between the common electrical contact and the base-level electrical contact being electrically closed by moisture to generate a base-level alarm signal, and responsive to a path between the common electrical contact and the first-raised-level electrical contact being electrically closed by moisture to generate a second-level alarm signal. Alternatively, a first pair of electrical contacts and a second pair of electrical contacts may be used.
