Hydrocarbon vapor sensor and system |
摘要 |
A hydrocarbon vapor sensor which is simple and low cost and can easily detect the existence of hydrocarbon vapor. The device is temperature compensated so that a change in resistance due to a change in temperature is avoided and an arcurate response is always provided. The sensor can be used in a system in which a number of sensors are provided at various depths to determine whether a leak or a ground spill has occurred.
