RTD Cables are used as an extension wire to transmit Signal from RTD Sensor to Control Unit. They are available in 2,3,4,6,8, 9 cores as per the requirement of RTD SENSOR design for Simplex & Duplex Construction.
The most popular design is of PTFE Insulation & outer jacket of PTFE, GLASS FIBER & SILICONE RUBBER as per requirement. Metal over braid of SS & SPC, if required
ELTEC PTFE Insulated RTD Extension wires conforms to US Military MIL - W - 16878 and Indian defense specifications JSS 51034. As per these standards, these wires are classified in three main working voltage grades.
