Differential Pressure Transmitter - Low Pressure - Wet / Wet

AST5100

Differential Pressure Transmitter product photo - AST5100

The AST5100 Differential Pressure Transmitter is your accurate pressure sensing device for low differential pressure. With a differential pressure ranges 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.

Benefits

- Accurate Low Pressure Measurement
- Excellent Repeatability
- Wide Variety of Liquids and Gases including:
Water, Natural Gas, Hydrocarbon Fuels, Air, Non-Corrosive Gases

Applications

- Liquid Level Control including Bubbler systems
- Climate / HVAC Controls
- Energy Management
- Air-fuel Ratio including Measurement for Furnaces
- Vapor Recovery
- Leak Detection
- Air or liquid Filtration
- Flow Measurement
- External Tank Level

Wetted Materials
- Nickel Alloy 52, Ni-Span C, Viton, 304 stainless steel
- Aluminum 6061, Solder, Loctite 680 (meets NSF61)

Installation Guidelines
The AST5100 must be mounted on a flat surface within ±15° to the ideal 0° plane to maintain specifications. Do not Over-tighten 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 P1will 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.
