New sil 2 3 certified vortex meters for safety instrumented systems reduce process downtime and prevent spurious trips.
Sil 2 flow switch.
The rosemount 2130 is sil 2 certified for safety instrumented systems.
The production of a safety instrumented system must be done with the best sil certified instruments to obtain reliable information for safety instrumented systems iec 61511 proper instrument specification and implementation is crucial.
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.
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.
It is a plug and play device which means that it is easy to install and does not require any advanced configuration or calibration.
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.
It is also virtually unaffected by process conditions which makes its measurements extremely reliable.
Our thermal dispersion flow switches are specifically designed for the harshest of applications in liquid or gas.
Thermal dispersion technology measures the temperature difference between an active heated rtd and a reference un heated rtd.
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.
Rated sil 2 fmeda.
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.
Single stage external cage float level switches.
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.
A tip sensitive lower gap allows measurement to within 1 4 of the vessel bottom.
