STN Temperature Transmitters: Proven IEC 61000 EMC Performance
We’re pleased to announce that STN Instruments’ temperature transmitters have passed IEC 61000 electromagnetic compatibility (EMC) testing for industrial environments. This certification validates that our transmitters measure accurately and operate reliably amid electrical noise, surges, and power disturbances common on factory floors and in critical facilities.
What Was Tested
Our transmitters were evaluated to the IEC 61000 family, including:
· Immunity (industrial): IEC 61000-4
– ESD: IEC 61000-4-2
– Radiated RF immunity: -4-3
– EFT/Burst: -4-4
– Surge: -4-5
– Conducted RF immunity: -4-6
– Power-frequency magnetic field: -4-8
Why It Matters
- Data integrity under noise: Stable 4–20 mA and digital outputs even near VFDs, relays, welders, and radios.
- Uptime & safety: Resilient to bursts, surges, and brownouts—no lockups, fast recovery, no surprise trips.
- Compliance & audit-readiness: Supports CE/UKCA routes and supplier qualification for GMP/FDA and ISO environments.
- Lower total cost: Fewer nuisance resets and service calls; longer field life.
Built for Real-World Conditions
STN’s EMC performance comes from:
- Input/output surge and ESD protection,
- Galvanic isolation and robust power filtering,
- Shielded enclosures and careful PCB grounding/layout,
- Firmware designed for fault detection and graceful recovery.
Where You’ll See the Difference
- Pharma & biotech cold chain (freezers, stability rooms)
- Refinery & process plants (motors, MCC rooms, VFDs)
- HVAC & building automation (mixed-vendor networks)
- Laboratory & production QA (traceable measurements)
