用于液体和轻质固体散料物位测量的限位开关
优点
- 对高粘度介质自动进行粘附补偿
- 按下按键即可简单快速地进行组态设置和仪表标定
- 获得了多项证书和认证,应用范围广泛
- 与介质接触部分由抗腐材料和FDA认证的材料制成
- 具有两级防罐体放电(气体放电和保护二极管)的过压保护
- 测量值反应时间短
- 更换电子插件无需重新标定仪表
- 自动监控电子插件的状态
应用领域
Liquicap M FTI5x用于限位检测,特别适用于以下测量任务:
- 高粘度和容易形成粘附的液体介质
- 不同液体介质的界面检测(如:水和原油)
- 仅采用一个过程连接即可进行两点控制(泵控制)
- 导电液体的泡沫检测
其经测试验证的坚固耐用的机械结构(锥形自密封)确保了探头既可用于真空环境,还可以用于压力值高达100bar的过压环境。采用的密封和绝缘材料使探头适用于操作温度范围为-80 °C ~ +200 °C的应用场合。
