Instrumentation and Plant Safety Case Study: Refinery Explosion


A case study of the 2005 BP refinery explosion in Texas City, TX. This video recaps the events and circumstances leading up to a catastrophic explosion. Contributing factors include inadequate level and safety instrumentation, as well as breakdowns in safety monitoring and standard operating procedures. This video, courtesy of the Chemical Safety Board (csv.gov) is an excellent educational reference and should be viewed by engineering, maintenance, and plant management personnel everywhere.

SOR Introduces the 1800 Series for Intrinsically Safe Applications and Conventional Transmitter Installations

The new SOR 1800 Series are available in 3 different models: gauge pressure measurement with standard over pressure rating, gauge pressure measurement with high over pressure rating, and differential pressure measurement.  The new line is well suited for intrinsically  safe applications or conventional transmitter installations where a compact footprint is impractical. The 1800 Series transmitters utilize an advanced monosilicon pressure sensor and incorporate a patented encapsulation technology to achieve exceptional mechanical and thermal isolation.

All 1800 Series transmitters include external push-buttons for device setup and calibration. If ordered with HART® output they can also be programmed with a HART® communicator. Additionally, they are available with 2, 3, or 5-valve manifolds. With a standard ±0.075% accuracy, the SOR 1800 Series conventional transmitters are an exceptional solution for continuous pressure monitoring.
