The measurement of barometric pressure in a free field can give values many hundreds of Pascals due to fluctuations and wind direction. With the static plug for barometric measurements HD9408PS 50 It is possible to reduce these errors to a minimum since not only it serves as a filter (brake) against the dynamic pressures of the wind, but it allows the barometer to work properly even in the presence of snow or ice and thus return to the recommendations WMO (Organization World of Meteorology). Materials used for manufacturing static hold are UV resistant and are able to work in temperature ranges from -40 ° C to + 80 ° C.
INSTALLATION AND CONNECTION
The installation is simple: it must take place far from any building, tree or other source likely to disturb the flow of the wind. For installation, a support bracket HD9408PS 56 and three M5x16 stainless steel screws are available. The connection of the static plug to the barometer, e.g. HD9408T or HD9408TR, is made using a special tube HV55 (internal Ø 3mm, external Ø 6mm) resistant to UV and climatic variations. Handling operations or cleaning are less. Plastic parts, produced by BASF, are in LURAN S777K. For cleaning use non-aggressive detergents compatible with the material.
