BEI传感器 full line of UL-certified nonincendive Division 2 encoders are now compliant to CENELEC/ATEX and IECEx non-sparking Zone 2 hazardous area standards. This triple certification is provided on six popular heavy-duty encoder models sized 2 to 4.5 inches in both hollow shaft and shafted versions. These models include the H20, H25, HS20, HS25, HS35, and HS45.
The non-incendive/non-sparking protection method assures that no sparking or hot surfaces will occur in the encoders under normal operating conditions. Encoders with this certification offer several operational benefits including simpler installation, no need for an associated apparatus (such as a barrier) and no restriction of energy to the hazardous location. These encoders also take up less space in the application and are often less costly than encoders designed for more stringent hazardous locations such as Division 1, Zone 0 or Zone 1.
这些危险区域编码者的三重评级也有助于简化最终用户组装的认证过程，并节省成本，以获得额外的批准以遵守国际安全法规。在仅在异常工作条件下存在爆炸性代理的应用中，可以使用非物质/非屏蔽编码器，而不是更昂贵的防爆或防火产品，这些产品超出了第2区和区域2环境的危险区域要求。
