High Purity Pressure Transmitter, Pressure Sensor(Replaced by the AST4000)

AST4900

AST4900 high purity electropolished pressure sensor product photo

The AST4900 is a media isolated high purity pressure transmitter intended for the measurement of liquids and gases. 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.
