1. Dual-Shielded Architecture: Individual Pair + Overall Screens for 90+ dB EMI
GAALFLEX® TRAY INSTRUMENTATION 600 SPOS utilizes dual-layer shielding with individual pair aluminum tape + PETP foil plus overall cable screen delivering 90+ dB comprehensive EMI suppression exceeding single-shield capability by 15+ dB.
High-EMI industrial scenario: A steel mill operates arc furnaces, induction heaters, and RF welding systems generating extreme electromagnetic noise. Traditional single-shield instrumentation (75–80 dB) tolerates industry EMI, but precision measurements degrade: RTD readings fluctuate ±5°C (±9°F), pressure transducers oscillate ±10%, control algorithms cannot stabilize. GAALFLEX INSTRUMENTATION 600 SPOS dual-shield (90+ dB): individual pair screens block local pair coupling, overall screen rejects facility-wide noise, EMI rejection 15+ dB better than single shield. Result: RTD stable ±0.5°C, pressure ±0.5%, control system tight, furnace efficiency improves 5–10%, product quality restored. Facility productivity gains far exceed cable cost difference.
2. High-EMI Measurement Protection: Pair-Level Isolation with Cable-Level Rejection
GAALFLEX® TRAY INSTRUMENTATION 600 SPOS provides dual-layer EMI protection architecture: individual pair screens isolate measurement circuits from crosstalk, overall screen rejects external facility-wide electromagnetic interference.
3. ICEA E1 Color Coding: Permanent Instrumentation Identification with Dual Shielding
GAALFLEX® TRAY INSTRUMENTATION 600 SPOS implements ICEA E1 color code standard (black/white numbered pairs) providing permanent instrumentation conductor identification with dual-shielded measurement integrity.
