PVDF/PTFE Submersible Pressure Transducer

AST4530

The AST4530 submersible pressure transducer is constructed using PVDF
material and a PTFE diaphragm. Designed to measure liquid level of corrosive
liquids, the AST4530 features submersible PVDF cable, cord grip and housing.
The AST4530 features a conduit connection for turbulent installations such as
on-board ships, turbulent tanks, and rail cars.

Voltage and 4-20mA output signals allow users to interface for low current
consumption or long distance transmission applications.

The AST4530 is CSA157 certied to Class I Div 1, Groups C and D for use in

intrinsically safe areas with an approved barrier, ANSI/ISA 12.27.01 Single Seal
Approved and ATEX Exia IIB Class I, Zone 0, T4.

CAN/CSA C22.2 No 60079-0:11, ANSI/ISA 60079-0:09, CAN/CSA E60079-11:02,
ANSI/ISA 60079-11:11, CAN/CSA C22.2N.157-92, UL 913 (6th Edition)
