ABSTRACT:
A rigid cylinder is provided with small perforations to permit the entry of hydrocarbon containing liquids, gases or vapors, and the interior of the cylinder is lined with a sensor material which expands in the presence of hydrocarbons. The interior chamber enclosed by the sensor material is completely filled with an incompressible liquid, and one end of the chamber is sealed by a conventional pressure sensor so that the presence of hydrocarbons causes the sensor material to exert a pressure upon the incompressible liquid to create an output signal in the pressure sensor. A double-chambered device, with only one chamber being perforated and thereby exposed to the hydrocarbons, can be used to compensate the pressure sensor signal for ambient pressure or temperature changes.
