Simplex thermocouple with Insulated hot junction, giving protection against stray voltages, also allows for a full-check of insulation resistance after completion of manufacture.

G

Simplex thermocouple with Grounded hot junction. The hot junction weld is incorporated in the cap weld closure, providing a faster temperature response than an insulated hot junction. Not recommended in high temperature, highly corrosive environments. Insulation resistance and sheath integrity cannot be checked electrically after manufacture.

E

Simplex thermocouple with an Exposed hot junction, allowing for a very fast response.

N2

Duplex, Insulated thermocouple giving the same advantages as the insulated simplex version but allowing for two independent signals to be read simultaneously for control and/or monitoring/alarm.

N3

As N2 above but providing three insulated hot junctions.

G2

Duplex, Grounded thermocouple have the same characteristics as G above but providing two simultaneous signals.

G3

As G2 above but providing three grounded hot junctions.
