产品概述

Armored thermal resistor cable adopts the similar technique as armored thermocouple cable, only with different core wires. It can combine with Pt resistor component into socket armored thermal resistor.


Our factory produces Ni and Cu-Ni alloy armored thermal resistor cable core wires, with 3-cores, 4-cores, 6-cores and other specifications with outer diameter of 5～φ8 for users to choose.

Note: When the length is below 1m, it's roughly considered as 1m. When it's above 1m, inlsulation resistance is calculated as R≥1000/L










3) The core wire resistance difference

At room temperature, the difference between the resistance values of the cores is not more than 0.05 Ω / m.
