Differential Pressure Transducer

AST5300 AST53ED AST53EN

The AST5300 offers low differential pressure measurement ranges in high
line pressure applications with excellent burst pressure capabilities. The

AST5300 has no oil lled cavities and no internal o-rings to fail, making it

ideal for food and beverage, oil & gas, pharmaceuticals, semiconductor
industries and cold ambients.

LINE PRESSURE

The line pressure specication is the maximum pressure the AST5300

can see without damage. Any pressure applied over the listed number
will likely damage the transducer and will, at minimum, cause a perma­nent zero shift. Line pressure should be applied evenly to both ports
during start up and shut down. [ A Line pressure of 500 psi or less can
be applied to one pressure port with the other port at 0psi and will not
cause a zero shift of the output. Pressure above 500 PSI to one side
may cause a temporary zero shift. ]

To recover from a zero shift caused by negative over-pressure to “L”
(low / downstream process connection) within the listed limits, apply
a positive over-pressure “H” (high / upstream process connection) to

1,450 PSI for a duration of ve minutes. Remove the over-pressure

and check the zero with no pressure applied. If the zero has not
recovered, repeat the positive over-pressure and recheck zero. If it
has not recovered after the second try, the zero has been permanently
shifted. Contact the factory.
