The 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. 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. Scale on the cross bar indicates the dial gauge position.

Strain gauges are of the same gauge factor and the gauges are fitted onto the diaphragm at different angles and radii. 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.

Instruction manual is also included.
