Dwyer A-301-A Static Pressure Tip, for Metal Tubing

Dwyer, A-301-A, Static Pressure Tip, for 1/4" Metal Tubing Connection with 6" Insertion Depth

These sensors are for use with Manometers, Magnehelic® Gages, Pressure Switches and other Controllers to pick up or sense static pressure drop across air filters and cooling coils, blower input and discharge pressures, etc. These static pressure tips are ideal for applications such as sensing the static pressure drop across industrial air filters and refrigerant coils. Here the probability ofair turbulence requires that the pressure sensing openings be located away from theduct walls to minimize impingement and aspiration, and thus ensure accuratereadings. For a permanent installation of this type, the Dwyer No. A-301 Static Pressure Tip is used. It senses static pressure through radially-drilled holesnear the tip and can be used in air flow velocities up to 12,000 FPM. The angled tipsshown have 4" insertion depth. Each has four radially drilled .040" sensing holes.
