2Precautions
& The armored tube type can be bent (minimum bending radius: armored tube diameter × 5), but the part of the temperature
detection range (20mm at the front end) cannot be bent; the protection tube type cannot be bent for use, otherwise it will
not measure the temperature correctly.
& To connect long thermocouple wires, be sure to use the compensating wire.
& Please strictly observe the heat resistant temperature of each part in product page. Please note that even the upper limit
of the temperature measurement is very high, if the heat-resistant temperature is exceeded, it may occur wire breakage or
disconnection problems.
& Do not apply large external force or vibration.
& Please note the heat-resistant temperature of the sleeve part.
& The upper limit temperature is only the value at the temperature measuring point (the front end of the armored tube).
During actual temperature measurement, please note that the temperature of the sleeve should not exceed the heat-
resistant temperature (80°C). Otherwise, the wire may be broken due to thermal expansion inside the sleeve.
Especially when the temperature of the heated object exceeds 100°C, please try to use the specification with a longer
length L of the armored tube, and try to keep the sleeve away from the heated object.
& Please keep the upper limit of the temperature below the temperature measurement range of the product. If the bushing
temperature exceeds the heat-resistant temperature, there is high possibility to cause wire breakage problem.
& If the temperature of heat generating parts exceeds 100°C, please choose the specification with a front end as long as
possible.
2Usage Method
Thermocouples should not be installed too close to the heater, the installation depth should be at least 8 to 10 times the diameter of
the armored tube. The gap between the armored tube and the thermocouple wall if not fi lled with insulation may cause overheating or
cold air to enter the heating chamber. Therefore, this gap must be fi lled with insulating material such as insulating earth or asbestos
to stabilize the heat in the chamber. Air convection aff ects the accuracy of the heating process. The sleeve should not be installed too
close to the heating chamber to avoid exceeding 100°C. The installation of the thermocouple should be avoided as much as possible
from strong magnetic and electric fi elds. Therefore, the thermocouple and power cable should not be installed close to each other
to avoid errors caused by signal interference. Do not install the thermocouple with the media. When measuring the gas temperature
inside the tube, the thermocouple needs to be installed in the opposite direction of circulation and in full contact with the gas.
