This leakage tester for buildings connects to Swema 3000md.
Swema 3000md saves measuring protocols and a report can easily be generated in excel. According the European norm EN13829 rooms and buildings shall be tested at minimum 5 different pressures. By pressing on the instrument keyboard the Swema 3000md controls the tester to test at minimum 5 pressure levels up to for example +50Pa. Maximum pressure is 100Pa. A leakage level is saved for together with each pressure level. The same measuring serie is possible to run at negative pressures.
Additional to Swema 3000md, that has a built-in differential pressure sensor, another differential pressure probe, SWA 10, is connected.
The built-in pressure sensor in Swema 3000md measures the pressure in the in the building. The connected pressure probe, SWA 10, measures the leakage flow across the orfice plate.
An axial fan is used to be able to provide highest possible flow at these moderate air flows.
Tighten the ventilation supply and exhaust with tighness bladders.
