Sil 2 Flow Switch

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.

Sil 2 flow switch.

Thermal dispersion technology measures the temperature difference between an active heated rtd and a reference un heated rtd. 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 a plug and play device which means that it is easy to install and does not require any advanced configuration or calibration. 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. Our thermal dispersion flow switches are specifically designed for the harshest of applications in liquid or gas. 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. It is also virtually unaffected by process conditions which makes its measurements extremely reliable.

A tip sensitive lower gap allows measurement to within 1 4 of the vessel bottom. 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. The flow through upper gap allows up to a 125 318 cm separation between switch points.

Changes in flow velocity directly affect the extent to which heat dissipates and in turn the magnitude of the temperature difference between the rtds. Rated sil 2 fmeda. Single stage external cage float level switches. New sil 2 3 certified vortex meters for safety instrumented systems reduce process downtime and prevent spurious trips.
