The objectives of project are to study the changes of pressure and comparison of the pressure of the equipment of measuring tools. To use as a learning instruments and measurement equipment in the industry. The students know methods quantify mechanical. The experimental device is cylinder hydraulic diameter of 20 mm. Stroke 50 mm. And pressure can be adjusted to the pressure exerted on the diaphragm. smooth with a thickness of 3 mm. diameter 15 mm. Test methods lead weight scales to put the arm supporting the weight attached to the cylinder to compress hydraulic oil to the pressure cooker to make the disc diaphragm rapid expansion.
The results found that measurement pressure measuring transducer diaphragm type. The force is measured with a resolution of up to the third decimal. The average value through to find the error is different at least until no the difference and at that point calibration and found no faults at all. The percent error may result from the chemical properties of materials. Loss of signal and the friction resistance of electrical equipment.
