The AST4900 pressure sensor is for use in the measurement of gases and liquids in semiconductor and other high purity applications. Using Krystal Bond technology, sensors have no oil-fill, welds, or internal O-rings and hold a CE EN61326 certification and UL/cUL508 approval. Units are available with 1/4-in. NPT male and 1/4-in. VCR male fittings. Each sensing element is machined from 316L stainless steel and electropolished to remove any contaminates; it can also be manufactured with Inconel718. Pressure ranges extend from 0-25 psi (0-2 bar) to 0-10,000 psi (0-700 bar), and compound ranges are also available. Available outputs include high-level voltage, current, and frequency, and units can be packaged with cable, DIN 43650 (form C), and Bendix (6 pin) electrical connections.
