INTRODUCTION
Vaisala model SPH10 Pressure Head provides an effective
elimination of pressure variations in the barometer due to the
wind. The SPH10 is easy to clean and maintain. It can be
integrated directly with the Vaisala PTB210 barometer. To other
barometers the SPH10 can be connected with pressure tubing.
ASSEMBLING
1. Screw the lower bar to the threaded sleeve of the lower
plates (with 6 holes)
2. Screw the upper bar (with mounting plate) to the threaded
sleeve of the upper plates
MOUNTING
Select an open location, prefereably a place higher than the
surroundings, with no buildings or trees nearby. Attach the
SPH10 to a horizontal pole using a mounting plate. A suitable
pole is Vaisala sensor mast, type DKP12. However, any other
horizontal pole with two screws (M6) in a distance of 41 mm can
be used.
NOTE! The recommended distance of the SPH10 from the
vertical pole should be at least 1.5 m.
1. Loosen the two fixing screws of the pole and fix the SPH10
into the pole as indicated in Figure 1.
2. Attach the SPH10 by tightening the screws. (The pressure
Head is removed by loosening the two screws).

(see figure 2)
1. Detach the threaded nipple and the gasket (see figure 1).
2. Place the O-ring into the barometer groove.
3. Attach the PTB210 to the SPH10 with two fixing screws.
CONNECTION TO THE OTHER BAROMETERS

a plastic tube with an inner diameter of 4 mm.
