  • Effective Compliance with IEC 61508 When Selecting Solenoid Valves for Safety Systems

    Regulatory modifications in 2010 have raised important issues in design and use of industrial safety systems. Certain changes in IEC 61508, now being widely implemented, mean that designers and users who desire full compliance must give new consideration to topics such as SIL levels and the transition from 1H to 2H methodologies.

  • Rocky Relationship Between Safety and Security

    This paper will discuss the methods used to ensure that the integration between the safety system and the BPCS DO NOT compromise Functional Independence and define best practices to secure an industrial system and in particular safety systems in this integrated environment.

  • Protecting Our Water – Keep Chemicals in the Tank

    Leaking or overfilled tanks containing chemicals, fuel oil, sewage or hazardous materials can cause environmental problems, contaminate drinking water and cost a company millions of dollars in fines and lawsuits. This white paper discusses instrumentation and controls that can monitor the contents of a vessel and provide an alarm in the event of a leak or overfill event.

  • Logic Solver for Tank Overfill Protection

    When a storage facility's tank level rises above safe limits, a logic solver that is part of a Safety Instrumented System (SIS) initiates final elements to restore the process to a safe state. This can include shutting off input feeds to the tank by isolating the pump and closing the input valve. This white paper explores the possibilities available to SIS designers of tank overfill protection systems when using a logic solver. It includes examples of system topographies and their associated Safety Integrity Level (SIL) calculations.

  • Wireless Security for Water/Wastewater Networks

    Wireless technologies have been used for decades in the water/waste water industry in a multitude of applications including tank level indication, pump and motor control, flow and pressure monitoring, etc. However, recent concerns regarding the potential for hacking and cyber-attacks into these wireless systems have raised the importance of wireless security to a new high. This paper will discuss security issues within an Industrial Wireless Network, and address the ways in which these networks can be designed to be more reliable while being more secure.
