Duplex Thermocouple

Duplex Thermocouples use two junctions in one sensor. Duplex Thermocouples are used in applications where downtime must be kept to a minimum, one sensor will be used until it reaches the end of its lifespan, then the wire can be quickly swapped round to the other junction and a replacement sensor can be ordered. If you use a 4-20mA Transmitter it can be setup to automatically move on to the 'back up' junction for zero downtime.

Duplex Thermocouples are also used in applications where two outputs are necessary e.g one output connected to a LED Panel Indicator and one output to a temperature controller.
