AST5100
The AST5100 Wet - Wet Differential Pressure transmitter is your accurate pressure
sensing device for low differential pressure. With a differential pressure range as
low as 0 to 5” water column (12.5mbar), this product can be used to measure flow
across an orifice, differential across a filter, tank level, or gauge pressure. Using
LVDT technology and AST’s advanced electronics, the AST5100 delivers accurate,
repeatable measurements.

Installation Guidelines
The AST5100 must be mounted on a flat surface within ± 15° to the ideal 0° plane to
maintain specifications. Do not Overtighten the pressure connections or insert any objects in P1 or P2 to avoid damaging the sensing element. When using isolation valves,
both should be mounted close to the sensor. For liquid level and wet applications,
install bleed screw adapters close to P1 and P2 so that trapped air can be purged if
needed. For optimum performance, always make sure pressure is equalized within the
pressure range chart ranges. The AST5100 has asymmetric protection on P1 and P2.

The over-pressure specification is the maximum pressure the AST5100 can
see without damage. Any pressure applied over the listed numbers will likely
damage the sensor and will, at minimum, cause a permanent zero shift.
Over-pressure between 2X span and the numbers listed applied to port P1
will likely cause no permanent harm. Over-pressure of between 2X span and
the numbers listed applied to port P2 may cause a temporary zero shift. To
recover from a zero shift caused by negative over-pressure to P2 within the
listed limits, apply a positive over-pressure P1 to just under the listed limit
for a duration of 5 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.
