Main technical indicators and choose thermocouple compensation wire release time: 2019 - 07 - 02 viewed: zero

Thermocouple compensation wire, compensation cable thermal electrode is used to extend the movement of the thermocouple cold end, and display instrument connection temperature measuring system. This product adopts equivalent by equivalent IEC584-3 'thermocouple part iii - compensation conductor should be' international standards, product quality is better than that of GB4989 - 85 the thermocouple with compensation lead national standards. Insulating layer and protective layer selects the import high quality fluorine plastic, and USES the new technology of the continuous extrusion, make the product with excellent acid, alkali, wear resistance and non-combustible delay of performance, can be immersed in oil and water medium and long term use. Using the temperature - 60 - 205 - 260 ℃, belongs to the contemporary international advanced level. Thermocouple compensation wire, compensation cable is mainly used in all kinds of temperature measurement device, has been widely used in petroleum, chemical industry, metallurgy, electric power and other departments. Thermocouple compensation wire main technical index 1, compensation conductor model according to the varieties of products are classified into: SC, KC, KX, EX, JX, TX, NC 2, including: a) Type the first letter with the thermocouple indexing number corresponds; b) The letter 'X' said expanded compensation conductor ( Don't type) ； c) The letter 'C' said compensation compensation conductor ( Don't type) 。 Note: SC type number can be compensation conductor with R type degree thermocouple thermocouple compensating conductor selection example: with K type coupling compensation wire, single nominal section 1. 5 was a senior general type with common compensation compensation conductor should be expressed as; KC - GB - VV - 2 * 1. 5 low heat by the level of precision block compensation type compensation conductor should be expressed as: KC2 - HA- FFP - 2 * 1. Low heat shielding cord with precision grade 5 expanded compensation conductor should be expressed as: KX - HA- FFRP - 2 * 1. 5 note: 1, compensation wire line core and line between core and blocking a finished product, the insulation resistance between the temperature of 20 ℃ when no less than 5 m Ω every 10 metres. 2, compensation conductor should be finished before and after heat aging temperature in 275 ℃ / 24 hours to five times the outer diameter of winding test, the voltage of 500 v / 1 minutes (no breakdown. 3, heat compensation conductor should be waterproof test, 1 out of the finished product. 5 m sample to end the leakage into the 40 + 2 ℃ thermostat, after 240 hours ( 10) Days later, the conductor line and the line between core per meter resistance value between the block and not less than 25 m Ω. 4 test with compensating conductor anti-acid, 1 out of the finished product. 5 m sample to end the leakage into the 40 + 2 ℃, the concentration of 95% sulfuric acid solution, after 240 hours ( 10) Days later, the conductor line and the line between the core and shielding between resistance should not be less than 25 m per meter Ω. 5, thermocouple compensation wire technology condition accord with IEC 584-3 standard, accord with GB4989 - general 85.
