Functional Features Low conductor resistance to minimize RTD measurement error. 3-wire structure to compensate cable resistance influence. High temperature resistant insulation for hot installation area. Full shielding design for resisting electromagnetic interference. Stable signal transmission for platinum RTD sensor. Flame retardant cable jacket.
Application Scenarios RTD sensor signal extension for Bently temperature monitoring module. Bearing temperature measurement of steam turbine and compressor. Power generation equipment temperature monitoring system. Petrochemical plant rotating machinery bearing temperature measurement. Industrial furnace and hot equipment RTD signal transmission.
Performance Parameters Conductor resistance: Low resistance to reduce temperature reading deviation Shield effectiveness: Suppress electromagnetic noise in industrial cabinet Temperature stability: Resistance value stable in wide temperature range
Structural Characteristics Three internal copper conductors, PTFE insulation for each wire. Whole cable wrapped by braided metal shielding layer. Outer high temperature resistant protective jacket. Cable ends stripped and ready for terminal wiring. Continuous length cable without intermediate splice point.
Working Principle The 3-wire RTD cable transmits resistance change signal of platinum RTD sensor to temperature module. The 3-wire design can eliminate the resistance error caused by cable itself. The shielding layer guides external electromagnetic interference noise to ground, preventing noise from affecting tiny resistance signal of RTD sensor and ensuring accurate temperature reading.
Installation Requirements Route cable separately from high current power cable. Avoid laying cable near high temperature pipeline where possible. Maintain enough bending radius, prevent sharp bending. Connect three wires strictly according to 3-wire RTD wiring definition. Connect shielding layer to single grounding point at module side. Fix cable properly to avoid pulling force on sensor connection point.
