本质安全防爆测温系统用热电偶补偿导线

Extension wire used in thermocouple for intrinsically safe explosion-proof 

Temperature testing system

 

一、产品特点及用途

    本产品采用密封绝缘和护套优于绕包编织的工艺结构,一般用聚氯乙烯绝缘和护套补偿导线,具有优良的防潮,耐磨和阻燃性能。耐热用氟塑料绝缘和护套补偿导线连续挤出工艺,更有耐高温、低温、耐酸、耐碱、耐油、耐磨、耐老化,防水不燃烧等优良性能。产品质量高于国家标准GB/T 4989-94(等效IEC584-3)的规定,热电动势允差均达A级精度。

    热电偶补偿导线用以延伸热电偶冷端,与显示仪表连接构成测温系统。

    本质安全防爆测温系统用热电偶补偿导线采用低电容、低电感结构,除具有上述热电偶补偿导线的性能外,还具有防爆安全性能。

本安热电偶补偿导线适应于有爆炸危险的环境及防爆安全性能要求较高的场合延伸防爆热电偶冷端与防爆测温仪表相连接,构成本质安全热电偶测温系统。

Ⅰ. Characteristics and application

The structure of product is sealed insulation and sheath, which is better than wrapped braiding one. PVC insulated and sheathed extension wire for general use has good features of moisture-proof, resistance to wearing and fire. Heat-resistance extension wire with fluoroplastic insulation and sheath is manufactured by new process of continuous extrusion. Its excellent properties include resistance to high temperature, low temperature, acid, soda, oil, wearing, aging, flame and water. The quality of the products is better than the requirement of national standard GB/T4989-94 (equivalent to international standard IEC584-3). Thermocouple allowance can reach A class precision degree.

The role of extension wire used in thermocouple is to stretch the clamp of thermocouple and connect with instrument to form a temperature testing system.

Extension wire used in thermocouple for intrinsically safe explosion-proof temperature testing system has a structure with low capacitance and inductance. Explosion-proof is its characteristics besides those in extension wire used in thermocouple.

The product is suitable for using in dangerous environment and places where high explosion-proof safety condition is required. The cold clamp of explosion-proof thermocouple is extended to connect with explosion-proof temperature testing system instrument, which forms intrinsically safe temperature testing system.
