Circular Diaphram

Product Code: LBNY-0005-1760004 - (Circular Diaphram)

Internal pressure is applied to the diaphragm by a hydraulic hand pump. Pressure in the diaphragm is indicated on a pressure gauge. A dial gauge is fitted onto a cross bar to measure the diaphragm surface profile. The Circular Diaphram equipment is used for studying the stress and deflection of a thin diaphragm. The circular aluminum alloy diaphragm is clamped around its edge by two heavy steel flanges. Each strain gauge is wired to form a full bridge with temperature compensation gauge and zero adjustment in a bridge box with strain gauge indicator. Scale on the cross bar indicates the dial gauge position. The strain gauges are fitted onto the diaphragm at different angles and radii.

Experiments:
Strains on the diaphragm surface under pressure.
Deflection of circular diaphragm under pressure.
