Pressure Instruments and Measurement INST 2112

• Upon successful completion, the student will be able to:

Safety

• Demonstrate safe working practices in the lab.

Pressure Measurement

• Convert pressure measurements among three standards: SI, MKS and BGS
• Define pressure types, such as atmospheric, absolute, gauge and vacuum.
• Identify zero, span & angularity errors when adjusting calibration to correct errors in gauges.
• Calibrate gauges using primary standards such as manometers and dead weight testers which are primary standards.
• Identify pressure gauges by type, class, application and gauge accessories, such as pulsation dampers, chemical seals and pigtail siphons.
• Calculate and correct for head effects on pressure and measurement.
• Identify receiver elements.
• Describe pressure switch contacts, such as mercury and micro switches.
• Calibrate pressure switches using appropriate test standards.

Pneumatic and Electronic Instruments

• Use a dead weight tester or a manometer to calibrate different types of gauges such as draft gauge, standard pressure gauge and high pressure gauge to manufacturer’s specified accuracy.
• Use the appropriate calibration test equipment to calibrate recorders including servo-mechanisms and other link and lever devices to manufacturer’s specified accuracy.
• Use the appropriate calibration test equipment to calibrate pressure pneumatic, electronic and smart electronic pressure transmitters using appropriate test equipment to manufacturer’s specified accuracy.
• Perform the set-up of a pneumatic relay.
• Explain the function of pressure measuring elements, such as bellows, diaphragm and helical.
• Describe force balance transmitters such as moment of force and true force.
• Describe motion balance transmitters such as angle motion and linear motion balance.
• Calibrate transducers (pneumatic to current and current to pneumatic).
