Downhole distributed pressure sensor arrays include sensor housings each comprising at least one pressure sensor in a pressure housing. Downhole pressure sensors include a housing, at least one pressure sensor in a pressure housing portion of the housing, and at least one isolation element positioned at an outer wall of the housing.

A downhole sensor array includes sensor housings, and each sensor housing contains one or more of a pressure sensor and a temperature sensor. Cable segments connect the sensor housings. A weld joint bonds a sensor housing to a jacket of a cable segment, and a conductor of the cable segment and the jacket of the cable segment may be separated by a void proximate the weld joint. Methods relate to forming such sensor arrays.
