Differential Pressure Transducer

The AST5300 wet/wet differential pressure transducer is for use in explosion-proof and non-incendive areas. Featuring all 316L and Inconel X750, the unit is suitable for various liquids and gases requiring high line pressure (1,500 psi) and low differential pressure (10 psid) measurements. The sensor is free of fluid fill cavities. Through the use of an LVDT and corrugated diaphragm, the unit measures differential pressure without any oil-filled capsules, thus eliminating potential risks of silicone oil leaks into the process fluid or gas. For high-purity gases and oxygen pressure applications, the unit can be sold cleaned and packaged to meet Praxair GS-38 standard.
