GB/T 36016-2018Sheathed continuous thermocouple cables and sheathed continuous thermocouple (English PDF)

2.1 Armored continuous thermocouple cable

The thermocouple wire is insulated with a heat-sensitive material and placed inside a protective tube, made of a compact, solid assembly that can be probed along the cable The highest temperature that exists is particularly suitable for temperature crossing alarms.

2.2 Armored continuous thermocouple

Continuous thermocouple made of armored continuous thermocouple cable.

2.3 Protection tube

A metal protection tube that protects the thermocouple wire and the heat-sensitive material from direct contact with the test object or the surrounding atmosphere.

2.4 Heat-sensitive material

Separates the thermocouple wire from the thermocouple wire, and between the thermocouple wire and the protective tube, and has a powdery inorganic substance having a negative temperature coefficient of resistance.

2.5 Working temperature range

The armored continuous thermocouple can stably output a measured temperature of the thermoelectromotive force signal corresponding to the highest temperature along the line for a long period of time. range.

2.6 Uniformity

The maximum temperature corresponding to the thermoelectromotive force obtained at several temperature-sensing positions distributed along the length of the armored continuous thermocouple at a specific temperature The difference in the minimum value.

3.1 Product Marking

The outer diameter of the cable connecting the temperature meter is 3.0mm, and the inseparable integrated joint and protective tube are used for the Incone1600 alloy.

For example, the double-core K-type armored continuous thermocouples are marked as follows. The meaning of each element in the tag is.
