点物位开关
带本安信号电路，可连接电容传感器
优点
- 本安信号电路EEx ia IIC，连接电容传感器可用于危险区域
- 通过操作键进行标定
- 极高的功能安全性:
- 故障安全的脉冲频率调制(PFM)或3-线制技术
- 可检查的继电器功能 - 一体化外壳，便于成套安装在机柜的标准DIN导轨上
- 插拔式的端子模块，接线方便
- 可以与EC16Z (PFM), EC17Z (PFM) 和EC61 (3-WIRE)配合使用
- 限值和报警继电器
- WHG 认证(PFM)
- 防止误操作和操纵
- 仪表设置改变时，红色LED亮并且给出一个出错信号
应用领域
- 限位检测，用于液体储罐和散装固体料仓。连接电容传感器可用于分类为ATEX II (1) GD的危险区域
- 用于易燃或非易燃液体、有害水的储罐的溢出保护
- 泵的空转保护
- 两点控制(Δs 采用 3-线制)
