摘要： The invention provides a sensor whose conductive sheet is composed of substantially non-cross-linked thermoplastic elastomer and conductive carbon. The conductive sheet has a maximum of 70 of Shore A-hardness. By virtue of the above structure, the sensor very sharply responds to electric resistance of the conductive sheet against presence of low molecular weight organic liquid such as gasoline and vapor thereof to quickly detect leaked organic liquid or vapor with extremely sharp sensitivity. Furthermore, the detection system of the invention using the above sensor has a simple circuit which precisely detects varied electric resistance of the conductive sheet. The detection system characteristically incorporates an alarm generator to instantly warn operators of the presence of leaked organic liquid such as gasoline and vapor thereof.
