CERTIFICATIoN AND FAILURE RATE DATA
All Safety-Certified FlexSonic Acoustic Detectors are
certified compliant to:
IEC61508: 2010
Type B Element
Systematic Capability: SIL 2 certified
HFT: 0
Low Demand Mode
PFDavg should be calculated for any safety instrumented
function using the FlexSonic Acoustic Detector. (Refer
to FMEDA report for necessary information, including
DU rate.)
Safety Accuracy:
±10% of applied acoustic leak
pressure.
Safety Response Time: Refer to the FlexSonic
Acoustic Detector instruction
manual for details.
Product Life:
10 years, based on
manufacturer data.
All failure rate data for SIL verification is in the FMEDA
report, which is available upon request.
ADDITIoNAL CERTIFICATIoNS
FM, CSA, ATEX, IECEx, CE, and others.
Refer to the FlexSonic Acoustic Detector Instruction
Manual for details.
For complete information regarding performance,
installation, operation, maintenance and specifications
of the FlexSonic Acoustic Detector, refer to instruction
