| 摘要 |
The present invention relates to a modular system for sensing pressure and/or temperature. The system uses a piezoresistive transducer that contacts a fluid, a transducer housing for the piezoresistive transducer, a conductor tube, a transition housing, a cable, an adapter housing, a flex conductor, an electronic housing, wherein the transducer housing, the conductor tube, the transition housing, the cable, the adapter housing, the flex conductor, and the electronic housing protect a conductive path for electrical signal(s) from the piezoresistive transducer to the electronic housing. The system may use cable to couple the transition housing to the adapter housing sufficient in length to keep the transducer at the site of interest and the more sensitive electronic circuits away from high pressure, temperature, and/or RF/EMI environments such as that associated with down-hole drilling. In another embodiment, some or all the conductive path is multilayered wire. |
