Pyro Electric Achieves IEC 61508 SIL Certification for RTD & Thermocouple Series

2025-12-28

Pyro Electric, headquartered in Goa, India, has successfully achieved IEC 61508 Proven-in-Use SIL certification for its RTD and Thermocouple product series 100–900.

The independent certification was performed by Risknowlogy and is based on real operational field data, extensive reliability analysis, and full compliance with the requirements of IEC 61508:2010.

This certification demonstrates that Pyro Electric’s temperature sensors are suitable for use in Safety Instrumented Functions (SIFs) in demanding industrial environments.


Certified Product Scope

The following RTD and Thermocouple series are included in the certification:

100 · 110 · 300 · 400 · 500 · 600 · 800 · 900

The certification applies to:

  • Low-demand safety applications

  • Type A devices

  • Hardware Fault Tolerance (HFT) = 0 for SIL 2

  • Redundant architectures (HFT = 1) enabling SIL 3 use


Certification Basis: Proven-in-Use According to IEC 61508

Unlike purely analytical assessments, this certification is based on a formal Proven-in-Use study, including:

  • 8+ years of operational field data

  • Hundreds of millions of operating hours

  • Data from Oil & Gas, Petrochemical, and Chemical installations

  • Independent statistical reliability analysis

  • Verified failure rate calculations (FIT, PFDavg, PFSavg)

  • Defined conditions of use and operating limits

This approach provides defensible SIL evidence that can be directly used by EPCs, system integrators, and end users during SIL verification and audits.


Why This Certification Matters for the Industry

For end users and EPCs, this certification:

  • Reduces uncertainty in sensor selection

  • Simplifies SIL verification activities

  • Strengthens audit and insurance defensibility

For product manufacturers and suppliers, it demonstrates that:

  • Functional safety competence can be proven with real data

  • Certification enables access to higher-value SIS projects

  • Products can be specified rather than substituted

  • Compliance is achieved through engineering rigor — not assumptions

Pyro Electric’s certification sets a benchmark for Indian manufacturers aiming to compete in global safety-critical markets.

A Message to Product Suppliers and Manufacturers

If you manufacture:

  • Sensors

  • Field instrumentation

  • Safety-critical hardware

and your products are already used — or intended to be used — in SIL-rated applications, independent certification is no longer optional.

Risknowlogy supports manufacturers worldwide with:

  • IEC 61508 Proven-in-Use studies

  • Product SIL certification

  • Reliability analysis and failure rate modelling

  • Audit-ready documentation

From data to certification — done properly.
