Industrial Automation is a discipline that includes knowledge and expertise from various branches of engineering including electrical, electronics, chemical, mechanical, communications and more recently computer and software engineering. Automation and control by its very nature demands a cross fertilization of these faculties, a vast and diverse discipline that encompasses machinery, electronics, software, and information systems working together toward a goal. Industries around the world are in the need to make sure process variable measurements such as pressure, temperature level and flow are precise and accurate. It is a fact that are subject to different environmental conditions, such as pressure, heat, dust, radiation, and many more factors that affect its performance this cause the instrument to have drifts making them not absolutely stable at all times. Calibration is the process of comparing measurements. Measurements are taken on two devices the first measurement being that of a known correctness and the second one being a similar measurement, on another device. The device holding the known correctness is referred to as the standard. The second device is commonly known as the test unit, unit under test, test instrument, or any other name given to the device that is being calibrated. Pressure gauges are used for a variety of industrial and application specific pressure monitoring applications. Uses include visual monitoring of air and gas pressure for compressors, vacuum equipment, process lines and specialty tank applications such as medical gas cylinders and fire extinguishers. On an analog pressure gauge the scale can be single or dual. A single scale displays one unit only, a dual scale displays in two units on the same face. Scale units can be PSI, kPa, bar, inches Hg, cm Hg, feet H2O, inches H2O, oz / in2, and kg / cm2. Common features of pressure gauges include adjustable pointers, maximum and minimum pointers, adjustable and stationary set hands, and electric contacts. An adjustable pointer has adjustment to zero the pointer via screw or knob. A maximum and minimum pointer indicates the maximum or minimum pressure attained. An adjustable or stationary set hand is a separate pointer (hand) to indicate a specifically set pressure. Instrument calibration is one of the primary processes used to maintain instrument accuracy. Calibration is the process of configuring an instrument to provide a result for a sample within an acceptable range. Eliminating or minimizing factors that cause inaccurate measurements is a fundamental aspect of instrumentation design. Although the exact procedure may vary from product to product, the calibration process generally involves using the instrument to test samples of one or more known values called calibrators. The results are used to establish a relationship between the measurement technique used by the instrument and the known values. Relationship between the measurement technique used by the instrument and the known values. They are also performed using only a few calibrators to establish the correlation at specific points within the instrument’s operating range. The demand for subtle living exponentially accelerates the requirements for knowledgeable engineers. The proposed project will be intended for College of Industrial technology students enrolled in Instrumentation and Control in Batangas State University. Many students need this calibrator to acquire learning and understanding things related...
