1. Dual-Shielded Triadic Architecture: Individual Triad + Overall Screens for 90+ dB EMI
GAALFLEX® TRAY INSTRUMENTATION 600 STOS utilizes dual-layer shielding with individual triad aluminum tape + PETP foil plus overall cable screen delivering 90+ dB comprehensive EMI suppression exceeding single-shield capability by 15+ dB while maintaining three-wire circuit standardization.
High-EMI three-wire scenario: A specialty chemical facility operates powerful AC drives, induction heaters, and RF equipment generating extreme electromagnetic noise affecting three-wire RTD networks. Traditional single-shield three-wire (75–80 dB) tolerates ambient EMI, but measurement quality degrades: RTD readings drift ±7°C, three-wire lead resistance fluctuates ±20%, process control loops hunt and oscillate. GAALFLEX INSTRUMENTATION 600 STOS dual-shield (90+ dB): individual triad screens block inter-circuit coupling, overall screen rejects facility-wide noise, triple-wire balance preserved. Result: RTD stable ±0.3°C, lead resistance constant ±1%, process control tight, product quality improved, operator confidence restored. Facility justifies dual-shield cost with 8–12% yield improvement.
2. High-EMI Three-Wire Protection: Triad-Level Isolation with Cable-Level Rejection
GAALFLEX® TRAY INSTRUMENTATION 600 STOS provides dual-layer EMI protection for three-wire circuits: individual triad screens isolate three-conductor circuits from crosstalk, overall screen rejects external facility-wide electromagnetic interference.
3. ICEA E1 Three-Wire Color Coding: Permanent Black/White/Red Identification
