The product

These thermocouples are typically used in high temperature processes in furnaces in the ceramic industry, glassmaking, foundry and in places where the use of metallic protections due to high temperatures is not allowed, chemical attacks or sometimes at lower temperatures where the media or the environment atmosphere is harmful to metallic tubes.

Main application at temperatures between 1000°C and 1650 °C.

Characteristics

Type Characteristics Comments
T
Suitable for use in oxidizing, reducing, inert and vacuum atmospheres.
It has good corrosion resistance in humid atmospheres, suitable for measurements at sub-zero temperatures.
 It is not recommended at temperatures above 310°C

due to copper oxidation.
J Suitable for use in oxidizing, reducing,

inert and vacuum atmospheres.
It is not recommended in atmospheres with high humidity levels,  atmospheres containing sulfur above 540°C and at
temperatures below 0°C the iron wire becomes brittle.
E

They can be used continuously in oxidizing or inert atmospheres.

It is the thermocouple that has the greatest thermoelectric power, which allows

the detection of small variations in temperature.

 Not recommended in reducing atmospheres.
K Recommended for use in oxidizing or inert atmospheres. Widely

used at temperatures above 538°C.

 It is not recommended in reducing and sulfurous atmospheres

and at high temperatures and low oxygen concentrations.
N It is not recommended in reducing and sulfurous atmospheres

and at high temperatures and low oxygen concentrations.

 Deve ser protegido em atmosferas sulfurosas.
S / N Recommended in oxidizing or inert atmospheres.

They have great stability and precision at high temperatures.

Suitable for use at temperatures up to 1480°C
They must be protected with alumina protection tubes.
Continuous use at high temperatures causes grain growth, which can cause wire breakage.
They must not be used in vacuum and reducing atmospheres and at temperatures below zero.
B
Recommended for oxidizing or inert atmospheres. It has superior mechanical resistance to type S and is less susceptible to grain growth.
Suitable for use at temperatures up to 1700°C
 It must be protected with alumina protection tubes.

It must not be used in reducing atmospheres.
