A-303 Static Pressure Tip for 3/16" ID Plastic or Rubber Tubing with 4" Insertion

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 of air turbulence requires that the pressure sensing openings be located away from the duct walls to minimize impingement and aspiration, and thus ensure accurate readings. For a permanent installation of this type, the Dwyer No. A-301 or A-302 static pressure tip is used. It senses static pressure through radially-drilled holes near the tip and can be used in air flow velocities up to 12,000 FPM. The angled tips shown have 4˝ insertion depth. Each has four radially drilled.040˝ sensing holes. All except Model A-303 mount in 3/8˝ hole in duct. For portable use, a magnet holdsNo. A-303 in place.
