Refinery Wirelessly Monitors Junction Box Pressure

The refining company needed to continuously monitor the pressure in Z-Purge junction boxes around the refinery. These junction boxes were maintained at a low positive pressure to prevent process gasses from entering the junction boxes. These junction boxes are widely distributed throughout the plant. Previously these junction boxes were manually monitored by operators on periodic rounds in the refinery.

  • Machine Condition Monitoring
    Machine condition monitoring is the process of monitoring parameters such as vibration and temperature in order to identify changes that indicate a reduction in performance or impending fault. It is a necessary component of Predictive Maintenance solutions and allows maintenance to be scheduled prior to failure, or other actions to be taken to prevent damages to the machine and loss of production. Condition monitoring also provides value beyond improving maintenance schedules. For example, improved visibility into machine operations can indicate the root causes of product defects and can support optimization of energy consumption.

  • SOLUTION
  • The problem was solved by monitoring the Z-Purge junction boxes with Rosemount 3051S wireless pressure transmitters. Each Z-Purge junction box was monitored for proper pressure on a continuous basis. The wireless solution eliminated the need to use existing spare wire capacity to monitor the junction boxes.
