331HF Shielded Triads Instrumentation Cable is specifically engineered for three-wire measurement systems in demanding offshore and marine environments worldwide. Unlike two-conductor pairs, each triad contains three conductors (Black-White-Red color coded) with a bare tinned drain wire, individually shielded with polyester-backed aluminum foil tape providing 100% coverage for superior electromagnetic interference (EMI) protection. The three-conductor design is essential for RTD (Resistance Temperature Detector) circuits requiring lead wire compensation, three-wire transmitter connections, and balanced instrumentation systems. Available in configurations from 1 to 8 triads in 16 AWG, this cable maintains circuit integrity during fire conditions while delivering exceptional signal accuracy for temperature measurement, process control, and critical safety instrumentation.
