2. For Thermocouple Elements,
select model number from Table I
followed by a letter selection from
Table II plus desired length equal to
the specified length plus 2 inches (51
mm) of exposed bare thermocouple
wire.
Example: 2K3M22-R48 = Type K
with Inconel sheath 4.8 mm (0.1 88”)
diameter, remote junction and 48
inches long.
3. For Assemblies, select model
number from Table I followed by a let-
ter selection from Table II plus
desired length of element in inches
and the cold end termination
designation from Table Ill. If mounting
attachments and wire extension ter-
minations are needed, make selec-
tions from Tables IV and V. Select the
required length of insulated extension
wire in inches from Table VI.
1. For Bulk MegopaK Material, select
model number from Table 1, and
specify length in inches. Longest
length available depends on sheath
diameter. Example: 2T1 Ml 5-60 =
Type T with 316 SS sheath 1.6 mm
(0.063”) diameter and 60 inches
long.
Example: 2J1Ml5-G24-9S-D12-
3W2J36 = Type J with 316 SS
sheath 1.6 mm (0.063”) diameter in-
tegral junction, 24 inch sheath
length, 12-inch wire extension length,
316 SS compression fitting, 20 gauge
insulated extension wire with fibre-
glass insulation, QuiK-Konnect jack
termination on extension wire.
