Safety Instrumentation

Fiber Optical Safety Instrumentation Level SIL 2, SIL 3 , SIL 4




The fiber optic technology today allows the development of solutions for safety instrumentation, control and detection levels with high operating safety. Many components used in the production of products offered by LIGHT GUIDE SOLUTIONS come from the telecom field and have very high and widely proven reliability levels. Thus, the solutions implemented by LIGHT GUIDE SOLUTIONS meet the requirements of Reliability Availability Maintainability and Safety (RAMS).


The systems of control/measures/detections – developed according to IEC Standard 61508 – can meet different derived standards, either for the nuclear sector (IEC61513), the railway sector (EN 50126 / EN 50128 / EN 50129), safety machines (IEC 62061 and ISO 13849), automotive (ISO 26262), industrial processes (IEC 61511) or medical devices (IEC 62304).


LIGHT GUIDE SOLUTIONS supports its customers in the development, production, installation and maintenance in operational condition (MCO) of security systems whether SIL1, SIL2, SIL3 or SIL4 (Security Integrity Level). The use of fiber optic sensors in safety instrumentation, particularly those based on Bragg grating technology, has the advantage of enabling solutions with a high level of reliability, particularly important in sectors such as aerospace and nuclear. The diagnostic possibilities are many and safety is at the heart of the sensor.
