FB 5000 Float Type Level Switch

FB-5000 is a compact designed float type level switch. FB-5000 is installed on the tank side and alarm contact will be actuated when the liquid level reaches the set point. FB-5000 is installed onto tank side nozzle or through an external chamber which is led from the tank. The liquid contact portion and electronics are perfectly isolated for safety operation.

Very small flow rate can be covered:  Min. 0 - 0.5 L/h [Water] can be measured.  
 Alarm output option available:    In addition to local indication type, alarm output version is also available.
 Compact design:   Easy installation onto instrument panel.
 Safety for high temperature and pressure: All metallic material construction covers tough applications!
