American Sensor Technologies (AST) has released the AST5300 wet/wet differential pressure transducer    for use in explosion-proof and non-incendive areas. Featuring 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 psdi) measurements. 

The sensor is completely free of fluid fill cavities. Through the use of a linear variable differential transformer (LVDT) and corrugated diaphragm, the AST5300 measures differential pressure without any oil-filled capsules. This eliminates potential risk of leaks of silicone oil into the process fluid or gas, according to AST. 

For high-purity gases and oxygen pressure applications, AST offers the AST5300 cleaned and packaged to meet the Praxair GS-38 standard. The DP also can have full-line pressure of 1,500 PSI applied to either process connection without damage to the transducer. This can eliminate the added cost of certain five-way valves and repair costs. 

Standard options include one-quarter-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.
