style="font-size:10.5000pt"><span style="font-family:宋体">利用电子秤的称重显示仪表，输出开关信号，经过三极管放大信号驱动继电器，使电子秤控制电磁阀的的开/关状态。电子秤必须有检重报警功能，设定检重报警值后就可以用重量控制电磁阀的工作状态，使之达到声光报警功能，此功能适用于生产企业成品检重等环节。</span></span></p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p><span style="font-size:10.5000pt"><span style="font-family:宋体">上下限报警电子秤的声音报警及三色灯报警方式：所谓上下限报警，就是设置好一个所称物品的 称重值（为上限），再设置一个所称物品的zui小称重值（为下限），设定好后，可以把电子秤定为限内报警（即在这个值里面的重量），也可把电子秤定为限外报警（即在 值和zui小值以外的重量）。三色灯顾名思义就是电子秤配有三种不同颜色的红，黄，绿三种颜色的报警灯，红色代表高出上限值，黄色代表低于下限值，绿色代表在上下限值内，并且电子秤灯光报警和声音报警是同步的。另外报警电子秤设定上限、标准、下限三段重量警示,可提示高、合格，低等五种报警状态（选配）,还可控制电磁阀、继电器等设备。全面支持PLC控制格式，通过开关量控制可以有效避免设备的电磁干扰。便于用户使用，同时大大的提高了企业的管理效益。</span></span></p><p>&nbsp;</p><p><strong><span
