One of the most common question that we are asked with our NoNonSensors SIL2 sensors is, why SIL2? Good topic for us to dig into!
SIL2 (Safety Integrity Level 2) is a classification under IEC 61508 and IEC 61511 standards that defines the risk reduction and reliability of safety-related systems, including melt pressure transducers and other industrial sensors. SIL levels range from SIL1 to SIL4, with higher numbers indicating greater safety and reliability requirements.
SIL2 ensures that a sensor or system provides a risk reduction factor (RRF) between 100 and 1,000, meaning it is designed to detect, diagnose, and respond to failures more effectively than SIL1.
Importance of SIL2 for Melt Pressure Transducers and Sensors
Higher Safety and Reliability – SIL2-certified melt pressure transducers are designed for fail-safe operation, ensuring consistent and safe monitoring of pressure in high-risk applications like plastics extrusion, chemical processing, and oil & gas.
Risk Reduction – In safety-critical applications, a SIL2 transducer minimizes the likelihood of dangerous failures that could lead to equipment damage, downtime, or hazardous conditions.
Enhanced Diagnostics – SIL2 transducers often include self-diagnostic capabilities, redundant sensors, and fail-safe designs that allow for early detection of faults.
Compliance with Industry Standards – Many industries require SIL-rated sensors to meet regulatory and safety requirements.
Improved System Integrity – A SIL2-certified sensor provides a more reliable signal, reducing false alarms, unnecessary shutdowns, or undetected hazardous conditions.
SIL2 offers 10 times better risk reduction than SIL1, making it more suitable for applications where failure could have serious consequences.
