AST4400

Intrinsically Safe Pressure Transmitter - Class 1 Div 1

AST4400 Class 1 Div 1 Intrinsically Safe Pressure Transmitter with Single Seal product photo

The AST4400 is a media isolated, stainless steel intrinsically safe pressure transmitter with a wide variety of options. In addition to its rugged construction and best price-to-performance ratio in the industry, the AST4400 is the solution for pressure measurement in Intrinsically Safe (IS) areas. It utilizes AST's proprietary Krystal Bond™ Technology, a one-piece stainless steel sensing element that offers excellent long-term stability and repeatable results.

The AST4400 pressure transmitter is also available with CSA Single Seal Approval to save customers the added cost of secondary seals required for Canadian installations.
