Description:
This course covers correct technology, operation, and maintenance of pneumatic instruments employed in modern process facilities. The emphasis is on valves, valve positioners, controllers, and transmitters.
You will be able to:
- Describe the operation of various pneumatic devices including bellows, diaphragm, Bourdon tube, flapper/nozzle mechanism, and pressure transmitters
- Discuss performance characteristics and identify errors associated with the operation of pneumatic measurement and control instruments
- Describe the specific tools used for pneumatic maintenance in a contemporary plant environment
- Discuss pneumatic air supply and components of air distribution
- Calibrate a differential pressure transmitter for a dip tube application
- Describe operation of various I/Ps (transducers)
- Discuss the function of a control valve and actuator in a typical loop
- Describe various types of actuators and positioners and discuss the characteristics and applications of each
- Describe valve/trim characteristics set by a pneumatic positioner and discuss the effect each has on loop performance
- Bench check and operate a pneumatic valve actuator, performing a five point calibration check on the positioner
- Perform a feedback control loop demonstration using a pneumatic controller
