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. With 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.

Note: ABS approval with CSA approved version.
