Power companies in old facilities face challenges relating to maintenance, repairs, replacement and upgrades. Often, the vendors that provided in-place instruments are long gone. Monitoring and control requirements may have changed. More or better process instrumentation may be needed to improve operations and decrease costs.

Moore Industries, North Hills, Calif., has released "Automation and Instrumentation Solutions for Power Plant Applications," a digital interactive line card that provides instrumentation solutions and applications for today's mature power plants. Topics include:
  • Installing distributed I/O to circumvent extensive new wiring installation and to monitor temperatures of the boiler tube, burner tip and cooling pump, in addition to tracking tank levels and archiving data.

  • Replacing and installing new signal transmitters, isolators and converters to convert legacy signals to standard 4 to 20 mA signals, and to convert low-level RTD and thermocouple signals to current signals that can better withstand transmission through a noisy plant.

  • Using process controllers, monitors and backup stations as hot PID backups for critical drum-level measurements, and as remote manual stations or field controls.
