  • Machine Functional Safety - PL and SIL Ratings
    This paper reviews the concept of Functional Safety as it relates to machinery. The design steps for a safe machine are outlined and the methodology for determining appropriate PL/SIL safety ratings discussed. The most common motion control Safety Functions are presented. The paper concludes
  • SIL 101 (Safety Integrity Levels): How Safe Do I Need To Be?
    The global importance of SIL (Safety Integrity Levels) has grown substantially in the. oil/gas, petrochemical and other process industries over the last 10 years. However, for. many end users, systems integrators, and product vendors, SIL is still a somewhat. ambiguous concept that often
  • Safety Integrity Level
    All organisational and technical risk reduction measures act as a counterweight to the risk potential. The values SIL 1 to SIL 4 (SIL = Safety Integrity Level) are derived from the risk analysis. The greater the risk, the more reliable risk reduction measures must be implemented and, consequently
  • News Machine Safety
    of safety standard. In future, elobau sensors and control units will have a SIL (Safety Integrity Level) category according to the IEC 61508 and a Performance Level (PL) according to the ISO 13849-1 in addition to the existing categories of the EN 954-1. For manufacturers this means that, independent
  • What does SIL stand for in safety?
    Nowadays safety systems saturate the industrial substructure, spreading protective influence all the way to an industry's end result. Modern safety structures minimize risk with effective enhancements that commonly increase dependability, proficiency and viability.
  • Selecting Instrumentation For Functional Safety (SIL) Applications
    Over the past couple of decades, the process industries have seen many changes when it comes to the design and implementation of emergency shutdown/safety systems. The introduction of several international and regional standards requires a more rigorous approach to the overall safety lifecycle
  • Functional Safety and SIL - What it Means to Plants
    The adoption of functional safety standards continues to grow rapidly worldwide. This trend is especially evident in process industries. Risk factors such as injury to personnel, production down time, environmental damage, litigation costs and tarnished corporate image have become more visible
  • ACHIEVING SAFETY INTEGRITY LEVEL (SIL) 3 CERTIFICATION
    In today's fast-paced industry, there are machines, systems and automation, that if a failure occurs, infrastructure, the environment, and lives could be put in danger. Sometimes the consequence of a failure can be truly catastrophic, resulting in significant damage and lost lives. While risk of
  • Safety Instrumented Systems Verification: Practical Probabilistic Calculations
    Safety Instrumented Systems Verification: Practical Probabilistic Calculations. Providing numerous examples, data tables, failure rate data and other important metrics needed, this book clearly explains how to do probabilistic calculations to accomplish SIL verification for safety systems.
  • What are Safety Integrity Levels and What do They Mean for Your Process?
    Safety Integrity Level (SIL) ratings are becoming more common. Many people are familiar with hazardous area approvals such as ATEX, IECEx and CSA; however, a SIL rating is slightly different.
  • Industry Solutions For The Most Common Solenoid Valve Challenges
    the solenoid valve, thus, allowing the orifice - from which water flows - to open and activate a sprinkler system. This helps keep the fire under control and prevent spreading to other parts of the building. Meeting SIL Standards. Solenoid valves must be of good quality and meet Safety Integrity Level (SIL
  • Emergency Isolation for Pneumatic Actuated Control Valves
    includes the memory-shape alloy FireChek (R) thermal shutoff with Versa's SIL Capable High Flow valve. The FireChek assembly provides a supplementary level of fire safety, while maintaining the original functionality of the specific valve in the process control system.
