RSA-CN Cable Float Level Switch
Applications & Features
- RSA-CN level regulator is a float switch to control the pump, valve or alarm.
- Applied to various kinds of liquid (non-corrosive, high temperature, light density or turbulence)
- Special designed multi layers structure proves the inner chamber very well sealed, gives safe and reliable protection for inside mechanism
- Non-toxic polypropylene(PP) float body, environmental friend, even for daily life water
- The ball shape has no any edges, is particularly suitable for sewage water
