AST5300 Ex Wet – Wet Differential Pressure Transmitter

AST5300 Ex Wet – Wet Differential Pressure Transmitter

The AST5300 wet/wet differential pressure transducer offers a maximum line pressure of 1,500 PSI. The AST5300 has no oil filled cavities or O-rings, eliminating risk of contamination and maximizing safety. Available in 4-20mA or voltage outputs, this differential pressure transducer can offer a cost effective alternative for flow, level and filtration systems in industrial, semiconductor, or oil and gas applications. The AST5300 can be configured as an explsion-proof or non-incendive differential pressure transducer for applications including natural gas filters and well head valve monitoring, and process flow measurement.
