型号描述
8111 是一种用于液体的液位开关，带有一个作为传感器元件的振叉。其设计适合工业中所有的工艺技术领域，可在液体中使用。典型用途是防止溢流或干运转。根据结构的不同，可将设备用于监督或控制易爆区域的液位，也可将其应用于可燃的液体、气体、雾气或蒸汽。8111 具有一个简单、耐用的测量系统，在使用时，几乎不受液体化学和物理特性的影响。它也可以在恶劣的测量条件下工作，比如涡流、气泡、泡沫形成、粘附、强烈外部振动或变换的填充物。
1）一般应用领域，比如液位采集或防止干运转
2）安装时不需设置
3）在表面粗糙度 < 0.8 μm 时，适合食品和饮料工业
4）ATEX 许可
Type Description
The 8111 is a vibrating level switch for liquids, using a tuning fork for level detection. It is designed for industrial use in areas of process technology and can be used in liquids. Typical applications are overfill or dry run protection. Depending on the version it is also used for monitoring or control of levels in hazardous environments, even for combustible liquids, gases, fogs or vapours. Due to the simple and rugged measuring system, the 8111 is virtually unaffected by the chemical and physical features of the liquid. It works even under unfavourable conditions such as turbulence, air bubbles, foam generation, buildup or varying products.
1）For universal use as overfill or dry run protection system
2）Setup without adjustment
3）For food and beverage industry thanks to surface finishing < 0.8 μm
4）ATEX approvals
