With an operating temperature of -40 to 80 degrees C, the AST4300 is ideal for use in many applications and industries, including process control, gas compression and storage, oilfield SCADA pressure equipment, test equipment and much more. 

Intrinsically safe pressure transmitter

The AST4400 is a pressure transmitter ideal for measurement in intrinsically safe areas. Like the AST4300, it utilizes AST's Krystal Bond Technology, a high strength stainless steel construction, and features no oil-filled cavities, welds or o-rings. It is also compatible with a wide range of liquids and gases.

With an operating temperature of -40 to 80 degrees C, the AST4400 is the perfect solution for a wide range of applications, including HVAC/R equipment, industrial OEM equipment, intrinsically safe control panels, pneumatic and hydraulic systems, and much more.
