AST5400 Differential Pressure Transducer
Brand: American Sensor Technologies Inc
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. 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.
