Wet / Wet Low Differential Pressure Transmitter

The AST5100 Wet - Wet 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.

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.
Workmanship - AST, Inc. pressure transmitters have a limited one-year warranty to the original purchaser. AST, Inc. will replace or repair, free of charge, any defective transmitter. This warranty does not apply to any units that have been modified; misused, neglected or installed where the application exceeds published ratings. AST’s sensors are made with pride in New Jersey, USA. If in the area please feel free to stop by for a visit!
Installation/Applications - The purchaser is responsible for media compatibility, functional adequacy, and correct installation of the transmitter.
