Abstract
An interface to provide coupling between a downhole sensor and wiring to other electrical equipment. The interface is configured to obtain voltage from a single power line and provide it to the downhole sensor while simultaneously converting sensor data to frequency form for transmission right back over the same power line. In this manner a substantial reduction in downhole wiring may be obtained. This may be particularly beneficial for sensors to be incorporated into downhole equipment where size and space issues are prevalent, particularly in the circumstance of equipment requiring a retrofit in order to accommodate the sensor capacity.
