PPE STYLE F flush mount T.C. can be installed in most nozzles. PPE STYLE M melt temperature sensing T.C. can be installed in
The special wire junction mounts flush with the internal nozzle bore most nozzles. The special sensing probe protrudes into the center
to avoid obstruction or damming the flow of plastic material. It is of the hot melt stream for precise temperature readings. Some care
completely replaceable and does not require costly welding or must be exercised to avoid damaging the probe. Avoid cold starts
factory replacement. or excessive molding pressure.

ISA Conductor Characteristics Temperature Limits of Error
Code Positive Color Negative Color Range (°F) Standard Special Application Notes
Iron Constantan 0 to 530 ± 4°F ± 2°F
J White Red Reducing atmosphere recommend.
(Magnetic) (Non-Magnetic) 530 to 1400 ± 3/4% ± 3/8%
Constantan -75 to 200 ± 1-1/2°F ± 3/4°F Can be used in oxidizing or reducing
T Copper Blue Red
(Silver Metal) 200 to 700 ± 3/4% ± 3/8% atmospheres: corrosion resistant.
Chromel Alumel 0 to 530 ± 4°F ± 2°F
K Yellow Red Oxidizing atmosphere recommended.
(Non-Magnetic) (Magnetic) 530 to 2300 ± 3/4% ± 3/8%
0 to 600 ± 3°F - Oxidizing atmosphere recommended
E Chromel Purple Constantan Red
600 to 1600 ± 1/2% ± 3/8% Highest emf output.
Platinum 0 to 1000 ± 5°F ± 2-1/2°F Oxidizing atmosphere recommended.
S Black Platinum Red
10% Rhodium 1000 to 2700 ± 1/2% ± 1/4% Easily contaminated.
Platinum 0 to 1200 ± 5°F ± 2-1/2°F Same conditions as 10% above but has
R Green Platinum Red
13% Rhodium 1200 to 2700 ± 1/2% ± 1/4% slightly higher emf.
G Tungsten White Tungsten Red 32 to 800 ± 8°F - Needs protective atmosphere such as
(W) 25% Rhenium 800 to 4200 ± 1°F - hydrogen, inert gas or vacuum.
D Tungsten Tungsten Similar to Type W except greater
(W3) 3% Rhenium 25% Rhenium 32 to 4350 ± 2°F - ductility in positive leg.
C Tungsten Tungsten 32 to 800 ± 8°F - Higher mechanical strength than Type W
(W5) 5% Rhenium White 26% Rhenium Red 800 to 4100 ± 1°F - Higher emf to 3400°F
Alternative to Type K. Longer life and better
N Nicrosil Orange Nisil Red 32 to 2300 ± 4°F -
stability than type K.
