What Is Duplex Thermocouple?

Duplex temperature sensors (dual element thermocouple) consist of a pair of temperature sensors within a single enclosure. For example, a duplex thermocouple would have two pairs of thermocouple conductors in a single sheath. Similarly, a duplex RTD sensor would have two RTD/pt100 elements at its hot end instead of a single element.

The main reason for a dual thermocouple configuration is to enable redundancy if one of the sensors fails. Duplex sensors cost more, but certain applications benefit from the redundancy gained. Peak Sensors can make all designs of duplex sensor, both duplex thermocouples and duplex pt100 sensors.
