Sil 2 Flow Switch

Rated sil 2 fmeda.

Sil 2 flow switch.

It is a plug and play device which means that it is easy to install and does not require any advanced configuration or calibration. The fs10i flow switch monitor is the only product in its class to carry a sil 2 compliance rating and has a superior 90 safe failure fraction sff. Delta controls is pleased to announce that the cs range of weatherproof atex iecex ex ia and ex d pressure switches have been assessed by sira certification service and found to meet the requirements of iec 61508 2 2010 as an element subsystem suitable for use in safety related systems performing safety functions up to and including sil 3 1oo2 or sil 2 1oo1. At preset rates ranging from 50 cc min to 100 gpm gems switches will initiate alarm actuation or automatic shut down of a.

Gems sensors offers a broad range of flow switch configurations for use in liquids or gases that feature high quality corrosion resistant materials for use in tough environments with material choices ranging from stainless steel to ryton for vast chemical compatibility. Changes in flow velocity directly affect the extent to which heat dissipates and in turn the magnitude of the temperature difference between the rtds. The rosemount 2130 is sil 2 certified for safety instrumented systems. Eden prairie minn january 30 2018 facilities with safety instrumented systems can now take advantage of the new sil 2 3 functional safety certification of emerson s rosemount 8800 vortex flow meters per iec 61508 which can help mitigate risk enhance plant safety.

Functional safety for process instrumentation and analytics since the iec 61508 and iec 61511 standards for functional safety came into effect demand has increased for process instrumentation and analytics devices conforming to the safety integrity level sil classification. Thermal dispersion technology measures the temperature difference between an active heated rtd and a reference un heated rtd. Single stage external cage float level switches. Our thermal dispersion flow switches are specifically designed for the harshest of applications in liquid or gas.

New sil 2 3 certified vortex meters for safety instrumented systems reduce process downtime and prevent spurious trips. They are both atex exd certified and sil2 rated. Fci flow switches feature thermal dispersion technology in which the temperature difference is greatest in a no flow condition and decreases as flow increases cooling the heated rtd. It is also virtually unaffected by process conditions which makes its measurements extremely reliable.
