危险场所选雷达,为什么不能只勾选“防爆”?

区域、气体或粉尘类型和具体证书范围必须相互匹配。

防爆是配置与应用条件的组合

气体危险区和粉尘危险区、不同保护型式和环境限制,不能用一个“防爆”标签全部覆盖。雷达的电气版本、温度等级、接液结构和附件可能影响适用范围。外形相同或系列名相同,不代表每个型号拥有相同证书。

由项目方提供现场分类要求

客户应提供所在国家或地区、区域分类、介质危险特性与环境条件,由专业人员核对保护型式及安装方案。IECEx等证书可通过官方系统核查状态和适用型号,但有证书并不自动代表在所有地区都满足当地使用要求。

采购和施工应使用同一批准版本

道威斯顿技术确认书应明确具体型号与所需证书,核对铭牌、附件和特殊使用条件。电缆引入、隔离设备、接地及开盖维护须遵循对应说明和现场制度;本文帮助整理选型问题,不能替代危险区设计与安装批准。

防爆适配审查所需清单

危险场所选型必须由项目专业人员提供分类依据,并将要求对应到每一个实际交付部件。

  • 登记使用国家或地区、区域分类及介质危险特性,区分气体与粉尘场所,并明确所采用要求由谁确认和批准。
  • 核对完整型号、保护型式、温度与环境限制、证书编号和状态,查看附件或特殊使用条件,不只核对系列名。
  • 检查电缆引入、隔离设备、接地及其他附件的适配要求,确认安装图与实际配置一致,不能由现场随意替换关键部件。
  • 把安装、检查和维护许可要求交给现场负责人,明确调试工具是否适合该环境;取得设备证书不等于批准所有作业。

假设审核:同系列证书与到货铭牌不一致

假设采购附件中有一张防爆证书,但到货雷达的完整代码或铭牌标识与证书范围无法对应。应暂停把这台设备视为已满足危险区要求,由供应商和项目专业人员核实,而不是凭系列外观相同或过去用过就投入使用。还应检查附件、特殊条件及当地接受要求是否一致。核实结果记录在交付与变更文件中,再按项目程序处理。这个假设说明证据必须对应实物,不提供现场带电开盖、临时改线或绕过保护的操作指导,也不代替区域分类和安装批准。
