The objective is to study the changes of values of pressure and pressure of comparison measurement device to be used as a device to measure the academic teaching entrepreneurs and industrial instrumentation, and allows students to know how to measure the amount of mechanical equipment and create pressure, using a hydraulic cylinder diameter. 20 mm. stroke 50 mm. and a set pressure can be adjusted, the pressure exerted on the diaphragm, flat sheet sizes, thicknesses, 3 mm. diameter 15 mm. how to test lead weights to place the arm supports a weight attached to a hydraulic cylinder compression pressure oil to the pot to make a diaphragm expansion occurs.
