106 is shown having optional seal glands 118 to facilitate pressure testing of sensor gauge assembly 100 prior to deployment stinger profile 110 of stinger head 106 is preferably constructed to align and guide sensor gauge 100 through a clearance port in a packer or other downhole device sensor port 108 allows sensors contained within main body 104 to communicate with fluids coming into contact with stinger head 106 readings from sensor gauge assembly 100 through sensor port 108 are reported back either to electronics not shown in main body 104 or to a remote location at the end of communications conductor 114 if main body 104 contains sensor electronics to process the signals read from sensor port 108 conductor 114 can be used to transmit the processed signals from main body 104 to a remote location for example sensor electronics inside main body 104 can contain digital processors so that communications conductor 114 extending from main body 104 to remote location through conduit 102 is a digital data path while the term u201c conductor u201d is used it is important that any communications mechanism hydraulic electrical and optical etc may be employed for communications conductor 114 without departing from the spirit of the present invention main body 104 of sensor gauge assembly 100 is preferably.
