AST4300 Non-Incendive Pressure Transmitter

AST4300 Non-Incendive Pressure Transmitter

The AST4300 is a Class I Division 2 Non-Incendive pressure transmitter for use in hazardous areas. In addition to its rugged construction and industry-leading price-to-performance ratio, the AST4300 pressure transmitter is the solution for pressure measurement for a variety of applications. 

AST can package the AST4300 pressure transmitter for indoor or outdoor use. It utilizes AST's proprietary Krystal Bond™ Technology , a one-piece stainless steel sensing element that offers excellent long-term stability and repeatable results. This MEMS technology completely isolates the media to all 316L stainless steel or all Inconel718, depending on the application. A variety of pressure port threads are available including 1/4" NPT and 1/2" NPT. Output signals are available for long transmissions (4-20mA) or low power (voltage) applications. 

The AST4300 pressure transmitter is also available with CSA Single Seal Approval to save customers the added cost of secondary seals required for Canadian installations.
