American Sensor Technologies Inc.’s (AST) AST5300 wet/wet differential-pressure transducer for use in explosion-proof and non-incendive areas features all 316L and Inconel X750 material. The AST5300 is suitable for various liquids and gases requiring high line pressure (1,500 PSI) and low differential-pressure (10 PSID) measurements. The differential-pressure transducer has a sensor completely free of fluid fill cavities. Through the use of an LVDT (Linear Variable Differential Transformer) and corrugated diaphragm, the pressure transducer measures differential pressure without any oil-filled capsules, thus eliminating potential risk of leaks of silicone oil into the process fluid or gas. Due to its oil-free design, the pressure transducer is a good fit for applications such as cryogenic level, pharmaceutical processing equipment, and gas compression systems. For high-purity gases and oxygen pressure applications, AST offers the AST5300 cleaned and packaged to meet the Praxair GS-38 standard. The DP can also have full line pressure of 1,500 PSI applied to either process connection without damage to the transducer. Standard options include ¼-inch NPT female process connections, 4-20mA, 0.5-4.5V ratiometric, 0-5V, and 1-5V output signals, and conduit electrical connections. Class I, II and III Explosion-Proof (AST53ED) and Class I Division 2 Non-Incendive approvals (AST53EN) allow for safe installation in hazardous locations. For non-hazardous locations, connectors and cable are available.
