Product Description

Description:

The Diaphragm apparatus allows students to examine the effectof pressure on the surface profile of a diaphragm. They can also determine thedistribution of circumferential and radial strains across its diameter. Asturdy base contains all parts of the Diaphragm apparatus. This forms a compactproduct, ideal for use on a workbench. Two heavy flanges clamp the edge of thediaphragm to provide built-in edge conditions. The area directly under thediaphragm contains oil. Eight strain gauges are cemented to the top surface ofthe diaphragm in various positions and at different radii. Each strain gaugecircuit is a full bridge, with high-stability resistors. The signals from eachstrain gauge are shown on a digital display. A digital dial gauge is fitted toa digital position indicator. The dial gauge can be traversed across thediaphragm to measure its surface profile. Both instruments can connect to optionalVersatile Data Acquisition System. Students use a hydraulic pump to increasethe oil pressure under the diaphragm. They record the strain readings anddiaphragm profile at different pressures.
