Perform Advanced Preventive, Predictive and Corrective Maintenance of Field Instruments
Course End Date:
This popular course offers a combination of practical information and hands-on experience, covering proper maintenance, calibration and troubleshooting of electronic, pneumatic, and smart instruments. You will examine characteristics of electronic control systems; techniques for all type of maintenance (preventive, predictive and corrective) of field instruments; and procedures for configuring and calibrating transmitters, transducers, and controllers.
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.
Also presents a systematic approach to troubleshooting and start-up of single and multi-loop control loops. You'll see how pressure, level, flow, and temperature loops operate to maintain good process control systems.
