Description |
N
|
 |
-
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.
