Abstract
A method for the selective detection of liquid phase hydrocarbons in the C.sub.6 -C.sub.16 range includes a matrix comprising a silicone polymer having dispersed therein a conductive carbon black filler of high structure and comprises signaling the presence of hydrocarbon liquid phase when the electrical resistivity of the sensor increases to a preselected threshold level intermediate the vapor and liquid phase resistivities.
