Traditional single-shield three-wire (75\u201380 dB) tolerates ambient EMI, but measurement quality degrades: RTD readings drift \u00b17\u00b0C, three-wire lead resistance fluctuates \u00b120%, 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 \u00b10.3\u00b0C, lead resistance constant \u00b11%, process control tight, product quality improved, operator confidence restored.
