Using Krystal Bond Technology, the AST5400 differential pressure transducer contains no silicone oil, O-rings, or welds. The low strain level on the diaphragm results in accurate, repeatable measurements. The AST5400 wet/wet differential pressure transducer is commonly used to measure differential pressure across filters or calculate flow across an orifice plates. With its digital compensation, the AST5400 DP offers excellent linearity and performance over temperature. The electronics offer a failsafe condition on the output signal. The AST5400 DP can be manufactured using 316L, 17-4 PH, Inconel 718, or Hastelloy C276 and is available for hazardous locations.
