Abstract
A sensor for the measurement of the hydrocarbon content in a flow of gas in a purge line. The sensor can measure the hydrocarbon content in the flow of gas in the purge line from a hydrocarbon storage device to an internal combustion engine. The sensor has at least one heating element and at least one thermal detector, with the heating element heating the flow of gas while the thermal detector determines the temperature of the flow of gas, which temperature is evaluated as a measurement of the hydrocarbon content in the flow of gas.
