Float level switch JYB/FQ-K type

Widely used for measuring various liquid levels, such as liquids in media such as oil, water, sewage, acid, alkali, etc. Adopting explosion-proof junction box and imported reed switch, guide rod and floating ball made of stainless steel material. In addition to measuring open liquid level, it can also be used for liquid level control and alarm of sealed containers with pressure<0.6MPa, working temperature -20 ℃~130 ℃. This product has a wide range of applications and high reliability.
