AST4700 Frequency and Voltage Output Pressure Transmitter

AST4700 Frequency and Voltage Output Pressure Transmitter

he AST4700 is a competitively priced, high quality pressure transducer intended for the use of measurement of liquids and gases. Utilizing Krystal Bond™ Technology, the AST4700 offers a one piece stainless steel sensing element free of welds, internal o-rings, and oil fill. This translates into rugged construction, high cycle life, wide range of media compatibility, along with all of the benefits of MEMs technology. The AST4700 can be packaged with a variety of process connections including NPT, SAE(UNF), and BSP. Voltage, current and frequency output signals are all standard choices when selecting an AST4700. Electrical connection options include cable, Hirschmann, and Bendix.
