Whessoe 200030-7851-1 是一款用于低温储罐系统的控制类印刷电路板（PCB），常见于液化天然气（LNG）或液氮等深冷设备的监控与安全控制系统中，负责温度、压力及液位信号的采集与逻辑判断，保障储运过程的安全稳定运行 。
该型号可能属于 Whessoe 公司 Cryogenic Storage Tank Control 系列产品线，与其相关的 200030-7851-2 型号已知应用于大型低温储罐的控制单元 ，推测两者在功能设计上具有高度相似性，差异可能仅体现在版本迭代或配置微调上。
其典型应用场景包括：
LNG 接收站、加气站中的低温储罐监控系统
工业气体生产与储存设施中的自动控制回路
与上位DCS/PLC系统通信，实现远程状态监测和紧急切断保护
