Description of Round Diaphragm Apparatus
Sturdy, compact, self contained bench top unit for determining the surface strains and deflections of a flexible diaphragm under varying pressures. An aluminium diaphragm is clamped rigidly around its outer edge, creating a volume underneath its surface into which oil is filled. On the top surface of the diaphragm are attached 8 precision strain gauges at differing orientations. Round Diaphragm Apparatus the diaphragm is flexed, the strain gauge output is fed into a digital display, which is supplied.
The force applied to the diaphragm is created by pressurising the oil underneath the diaphragm using a fine adjustment control mechanism. An analogue pressure indicator monitors the pressure, whilst an electronic pressure sensor monitors the same pressure but gives an output signal to the digital display.
