Differential Pressure Sensor for Liquids and Gases

The AST5400 wet/wet differential pressure sensor is designed to measure line pressures up to 2,000 PSI with a turndown ratio of 15 to 1. Using Krystal Bond™ Technology, the AST5400 contains no silicone oil, O-rings or welds. This MEMS pressure sensor technology completely isolates the media to the pressure ports, thus eliminating contamination risk. The low strain level on the diaphragm results in accurate, repeatable measurements. This differential pressure sensor, with its high line pressure capability, can be installed into systems without five way equalization valves, thus saving users hundreds of dollars per installation.
