产品概述

We produce armored thermocouple cable made of excellent class I thermal couple. It adopts excellent stainless steel and high purity magnesium oxide with advanced manufacturing technique, certified by GB/T 1840 standard, with fine performance. Its surface is brightened.

We can produce precious or base metal armored cable with various graduations and specifications, which are indispensable in the production of armored thermal couples. Base metal armored cable is available all the time while precise metal cable must be ordered in advance.

Graduation: N, K, E, J, T, S, R, B

Note: 1. when D=0.5, no S, R, B thermocouple is provided. 2.the wire length of precious metal armored thermal couple is decided according to the contrast. 3. Contrast decides the delivery length.

3) insulation performance

Model	Test Conditions					Mini-insultation Resistance MΩ·m
	Temp.	Test Temp. ℃	Diameter of Sample D/mm	Length of Sample L/m	Test Voltage V·DC
KK、KN、KE、KJ、KT、 KS、KR、KB	Room Temp.	20±15	≤φ1.5 ＞φ1.5	1	75±25 500±50	1000
KK、KN、KE、KJ、KT	High	500±15		0.5		5
KT		300±15				500
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 thermocouple.

4) the maximum working temperature and test temperature
