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 is 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).
CONNECTION TO THE VAISALA PTB210
Visualization in 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 OTHER BAROMETERS
Connect the barometer to the threaded nipple (Figure 1) by using
a flexible, airtight tube with an inner diameter of 4 mm. To
prevent condence water accumulation in the tube, make sure the
entire length of the tube goes downwards from the barometer to
SPH10.
