MEMS-Based SS Pressure Sensor
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.
