AST4900

High Purity

Media Isolated Pressure Sensor

Overview

The AST4900 is a media isolated pressure sensor intended for the measurement of liquids and gases in high purity applications. Utilizing Krystal Bond™ Technology, each sensor is free of oil-fill, welds and internal O-rings, all of which eliminate the risk of system contamination. This one-piece design also promotes high cyclical life, high shock and vibration capability and will maintain long-term stability, even in extreme conditions.

Benefits

♦ All 316L High Strength Stainless Steel Construction

♦ No Oil, Welds, or Internal O-rings

♦ Wide Operating Temperature Range

♦ UL/cUL508 Approved

♦ CE EN61326 Certified

Applications

♦ Gas Panels and Manifolds

♦ Test Stands

♦ Semiconductor Equipment

♦ Gas Pipeline Instrumentation

♦ Data Loggers

♦ Pressure Instrumentation
