摘要
A variety of pressure sensors have been tested in the laboratory for accuracy and long-term stability. The Paroscientific 215-AT, Rosemount 1201F1B, and Setra 270 were found to be the most accurate, maintaining 0.1-mb accuracy over long periods. These were followed by the AIR DB-1A with 0.5 mb in most units tested. The Paroscientific and AIR sensors require the least power and are the most suitable for remote deployments. Results on several inexpensive sensors show that some are worthy of consideration if accuracy requirements can be relaxed somewhat. The AIR DB-1A was selected for use in the barometric pressure module for the IMET (improved meteorology) system.
