The 230-61002 Gill Pressure Port provides an effective static pressure inlet for a barometric pressure sensor. Measurement performance of remote barometers can be seriously impaired by the effects of wind at the barometer inlet. Ambient wind of 20 meters/second blowing over a typical barometer inlet tube can cause dynamic pressure errors as high as 3 millibars.* These errors can make atmospheric pressure data useless for research and forecast purposes.
The Gill Pressure Port reduces dynamic pressure errors to a minimum level. The unique parallel plate design of the Pressure Port effectively slows air velocity at the pressure inlet. A simple internal baffle system creates a barrier to water and snow intrusion into the barometer.
The Gill Pressure Port features durable, corrosion resistant plastic construction for long service and minimum cost.
Barbed fittings are supplied for easy connection using 1/4 inch i.d. flexible tubing. The installation procedure is as follows:
