The AST4000 Industrial Pressure Sensor can be constructed as a millivolt output pressure sensor, amplified voltage output pressure transducer, or 4-20mA loop powered pressure transmitter.

AST's Krystal Bond™ Technology is the foundation of the AST4000. This leading MEMS technology gives the AST4000 flexibility to be used in virtually any OEM application. Whether measuring hydraulic pressure in a manifold or corrosive liquids and gases such as sea water or hydrogen, the AST4000 industrial pressure sensor provides a thick diaphragm to maintain long-term stability. Optional stainless steel materials include 316L and 17-4PH stainless steel. For more aggressive liquids and gases Alloy 718 is commonly selected.

The AST4000 Industrial Pressure Sensor is offered with a variety of process connections, multiple output signals (voltage and current), various electrical connections (cable, DIN, Eurofast and Deutsch) and is available in pressure measurements of gauge, sealed gauge and compound gauge.
