Abstract: Transmitter selection can be summed in general terms under a heading of ap plication. Even though generically speaking pressure transmitters are all the same, the fitness of use for transmitters is not the same. The total accuracy statement of a transmitter that has been hardened to withstand extreme co rrosive effects will not appear equal to a reference class transmitter. This kind of information is not within the scope of a transmitter data sheets an d there in resides a challenge fo r pusers. The history of oil and gas measurement has followed dir ectly the advances made in transmitter technology. As close as 10 years past total sight error budget of 3 - 4% was more the norm th an the exception. The transmitters used were for the most part analog and did not have the repeatabilit y or stability to support data where sight requirements were more stringent. Few of these sights were capable of meeting the TEB 1 over temperature and even fewer of the locations were able to meet the TEB when over pressure effects were added to the requirements
