VKK2R-8 Ex

HBM的VKK2R-8Ex EEx接线盒符合用于防爆外壳的ATEX 95。接线盒适用于潜在爆炸性环境中的称重传感器，例如石化行业中的卡车秤。使用接线盒可以将常规的标准称重电子设备连接到危险区域之外，而无需诸如安全栅栏之类的中间设备。新的接线盒可以轻松连接多达八个符合EMC要求的模拟应变计称重传感器。 VKK2R-8Ex EEx接线盒还具有符合EMC标准的公制螺纹电缆密封套，通过HBM的屏蔽设计可确保完全符合EN45501的EMC要求。接线盒具有内部电阻网络，以集成HBM的特殊，高精度和可靠的角负载平衡功能成比例。这意味着可以通过三个简单步骤获得结果：

HBM's VKK2R-8Ex EEx junction box complies with ATEX 95 for flameproof enclosures. The junction box is suitable for load cells used in potentially explosive atmospheres such as in truck scales in the petrochemical industry. Using the junction box allows customary standardweighing electronics to be connected outside the hazardous area without needing intermediates such as safety barriers.Up to eight analog strain gage load cells complying with EMC requirements can be easily connected to the new junction box. The VKK2R-8Ex EEx junction box also features EMC-compliant metric screwed cable glands to ensure full EMC compliance as per EN45501 thanks to HBM’s shielding design.The junction box features an internal resistor network to integrate HBM’s special, highly precise, and reliable corner load balancing feature into in a scale. This means that results can be obtained in three simple steps: 

• load scale corners,
• read correction value from diagram,
• activate balancing resistor.

 

This VKK2R-8Ex EEx junction box has been marked II 2 G/D and II3 for use in potentially explosive atmospheres and is supplied with the requisite PTB 05 ATEX 2014 type examination certificate issued by PTB (German Metrology Institute). The junction box can be used for protection in Zones 1, 2, 21, 22.
