Isolated choice pressure transmitter is best to use a threaded connection in the form of the transmitter brand, which saves money and convenient installation. For normal pressure and differential pressure transmitter selection, but also consider the issue of the measured medium corrosive, but medium temperature can not be considered as ordinary pressure change is the impulse to the table, long-term working temperature is room temperature, However, the use of ordinary maintenance than isolated large. The first is the insulation problem, in the northern winter minus transmitter brand, impulse pipe will freeze, unable to work or even damage to the transmitter, which need to increase heating and insulation boxes. From an economic point of speaking, the selection of the transmitter, if not easy to crystallize the media can use common transmitter voltage transmitter brand, but also for low pressure and crystallization medium can also be added to indirectly measure the purge media (as long as the process allows with a sweep liquid or gas), applying ordinary transmitter is required to maintain personnel conduct more regular inspection, including connecting pipe leaks, purging medium is normal, insulation is good, as long as safeguard the foreign pressure transmitter brand, extensive use common transmitter will save a lot of time investment. From the selection of transmitter measuring range, it is generally the transmitter has a certain range adjustable range, measuring range to be used provided the best in its range of 1/4 to 3/4 sections, such precision will be guaranteed, For differential pressure transmitter it is more important. In practice, some applications (level measurement) requires the transmitter measuring range migration is calculated according to the site installation position measurement range and migration, migration has a positive transfer and negative transfer points.
