Nowadays, safety in industry is becoming increasingly important. As a result, new standards are being introduced to ensure that production processes are carried out in a way that is safe for workers and the environment. One such standard is SIL, or Safety Integrity Level. In this article, we will discuss what exactly SIL is and which JUMO devices can help to secure SIL safety chains. Check it out!
SIL (Safety Integrity Level) ist ein Maß für das Sicherheitsniveau eines Systems, das sich auf das Risiko unerwünschter Ereignisse in industriellen Prozessen bezieht. Die SIL-Skala definiert die Anforderungen an die Konstruktion, Implementierung und Wartung von funktionalen Sicherheitssystemen.
SIL levels are determined for electrical and electronic safety systems on the basis of EN 62061
SIL safety chains play a key role in industrial processes where safety is an absolute priority. Properly securing technological processes against failures, accidents or explosions avoids many dangerous situations and also protects against financial losses. It is worth noting that in the event of errors or system failures, the consequences for the company can be very serious and involve not only financial costs, but also the risk of loss of health or life of employees.
SIL safety chains are used in various industries. SIL devices are used in the chemical, refining, petrochemical and energy industries, as well as in food and pharmaceutical production. Each of these industries requires specific solutions that must be tailored to the needs and requirements of the production processes.
In the oil and gas industry, where there is a risk of fires, explosions and leaks, SIL safety chains are an integral part of protection systems
SIL (Safety Integrity Level) is a scale that defines the required functional safety levels of equipment in safety systems. There are four SIL levels, numbered from 1 to 4, each corresponding to a specific probability of functional failure and potential risk to people and the environment. The higher the SIL level, the greater the reliability and safety requirements of the system.
Specifically, SIL levels define the minimum requirements for the functional safety of a system, where 1 corresponds to the lowest and 4 to the highest level of requirements. In other words, the higher the level, the more likely it is that the safety functions will function correctly. The definitions of the different SIL levels are shown below:
Correctly determining the safety levels of electronic and mechanical equipment requires knowledge of the standards and the ability to follow the risk and safety assessment procedure in practice.
JUMO safety chain devices SIL
JUMO Safety Performance is a new brand from JUMO, offering SIL qualified and PL qualified products for enhanced safety in safety applications, including SIL and PL certified devices and passive components for SIL and PL measurement chains. It includes devices such as:
JUMO Safety Performance devices - your starting point for implementing safety functions
In order to select the appropriate SIL level for your process, you need to carry out a risk assessment, which involves analysing your industrial process, identifying potential hazards and estimating the likelihood and consequences of each hazard occurring. Based on the results of this analysis, you can determine the level of SIL that is required to ensure an adequate level of safety.
When selecting the appropriate SIL safety chain device, several factors should be considered, including:

The correct assembly and configuration of devices are key to ensuring that they function correctly and are effectively linked in the SIL safety chain. Depending on the type of device, it may be necessary to carry out calibration and testing to ensure that it is operating according to SIL level requirements. It is also important to read the operating instructions and follow the manufacturer's recommendations for maintenance and service before operating the equipment.
