Tyco Thermal Controls, Menlo Park, CA, has integrated Power Line Carrier Interface (PLI) technology into its DigiTrace NGC-30 heat-trace control and monitoring systems. PLI technology lets the systems transmit RTD temperature information through the heat-tracing cable and power distribution wiring, eliminating the need for separate RTD wiring, reducing the time and costs involved in installing the heat-tracing system in the field. PLI allows temperature information from DigiTrace Smart End Seals and DigiTrace 700-TT transmitters to be sent back to the NGC-30 heat-tracing controller along the heat-tracing power lines.
