As SIL 3 has become a frequently discussed topic in safety-critical systems, it is particularly important to understand the definition, levels, and applications of SIL, as well as the specific meaning and applicable scenarios of SIL 3. This article will help you fully grasp the relationship between SIS and SIL, with a focus on the importance of SIL 3, aiming to assist you in making appropriate choices in practical applications.

To meet the emission standards for fly ash and flue gas generated by coal combustion, a large distillery added pulse bag filters during its technological transformation. The key feature of these filters is using high-pressure air to blow dust off the filter bags via pulse valves, collecting the dust in the hopper below. A level switch is employed to detect the fly ash level inside the hopper; when the level reaches a high point, it sends an alarm signal to prompt timely emptying of the hopper.

When selecting instruments, full consideration should be given to their anti-freezing and anti-condensation performance. Instruments with thermal insulation and tracing, as well as isolation tanks, should be chosen based on working conditions and media. Appropriate tracing methods such as steam tracing, electric tracing, or hot water tracing should be selected according to on-site conditions and explosion-proof requirements. Signal remote transmission instruments and display gauges must meet low-temperature resistance requirements, and the anti-freezing isolation fluid used should also be resistant to low temperatures.

The aging process of instruments before leaving the factory (also known as "pre-aging" or "burn-in") is a process step where manufacturers conduct continuous power-on, loading, or operation of the instruments for a period of time by simulating actual usage environments and working conditions, so as to pre-trigger potential faults and stabilize performance parameters.
