Abstract

An organic liquid sensor is provided that is configured to output a signal corresponding to the presence of one or more organic liquids. The sensor includes a circuit board, a sensor film deposited on the circuit board, the sensor film including a first segment, a second segment, and a bridge, the first segment and the second segment being electrically separated by a gap, and the bridge being electrically coupled to the first segment and the second segment. The circuit board is configured to detect a resistance of the sensor membrane.

Description

[0001] Cross References to Related Applications [0002] This application is based on, claims the benefit of, and claims priority to, U.S. Provisional Patent Application No. 62 / 895,790, filed September 4, 2019, and U.S. Provisional Patent Application No. 62 / 892,441, filed August 27, 2019, for For all purposes, it is hereby incorporated by reference in its entirety. Background technique [0003] Certain sensors can be used to detect organic liquids in the presence of other substances. For example, certain sensors may be used to detect hydrocarbons and / or oil in the presence of water, such as hydrocarbon fuel floating on water, spread on a flat surface, or collected in a sump. Such sensors could also be used to improve the safety of diesel generators used for backup power by detecting potential leaks. Sensors can be used for the same purpose to detect leaks near oil storage tanks used in oil-fired boilers or other heating-related equipment in commercial buildings. The sensor ...
