FB 7000 Float Type Level Switch

FB-7000 is a series of horizontal mount type, float level switch. FB-7000 is used for level alarm detection and pump control etc. FB-7000 has a magnet coupling system for isolation between tank portion and electronics side for safety.
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!
