Rockwell Online Vibration Protection System

Various machines were tripping on false vibration which used an integral sensor and transmitter.  Installing Rockwell's XM series of modules allowed machinery protection with online diagnostic capabilities.  This reduced machine down time by reducing false trips.  Installing the Emonitor software also enabled emails to be sent to the appropriate personnel prior to trip set points being reached and a database to review machine history.

Project Support

Procured instruments and valves for 250M gallon dry milling ethanol plant.  This included reviewing for correct specifications and specifying instruments for special applications. Provided instrument installation oversight and progress reporting.  Support for troubleshooting loop problems.  Modified initial layout of I/O panels to suit customer needs and assembled panels.

Instrument Air Dryer Upgrade

Air dryer valve actuators would routinely fail which caused loss of plant instrument air.  This resulted in unnecessary plant down time.  The PLC was replaced with a ethernet capable one and limit switches were added to the valves to alert operators of a valve failure.  A  transmitter was also installed for real time monitoring of instrument air dew point leaving the dryers.

Equipment Reliability Improvement

Determined component criticality for a nuclear power plant and analyzed existing preventive maintenance procedures.  Recommended changes to existing procedures as required to enhance equipment reliability.  Grouped components so that they could be taken out of service to have maintenance performed with minimal effect to plant operation.
