AST5400 wet/wet differential pressure transducers can measure the differential pressure of liquids or gases with line pressures up to 5,000 PSI (350 bar) and a turn-down ratio of 15 to 1. Using Krystal Bond Technology, the AST5400 differential pressure transducer contains no silicone oil, O-rings, or welds. This MEMSMicro Electro-Mechanical System pressure sensor technology completely isolates the liquid or gas to the process connections, thus eliminating contamination risk. The low strain level on the diaphragm results in accurate, repeatable measurements.
The AST5400 wet/wet differential pressure transducer can be used to measure differential pressure across a filter, monitor level tank, or calculate flow across an orifice plate. With its digital compensation, the AST5400 offers excellent linearity and performance over temperature.
The electronics offer a fail safe condition on the output signal.
The AST5400 can be manufactured using 316L, 17-4 PH, Inconel 718, or Hastelloy C276.
