FB-5000

FLOAT TYPE LEVEL SWITCH

OUTLINE

FB-5000 is a float type level switch which is installed at tank side through a nozzle or through an external chamber. The float follows liquid level and integrated reed switch is actuated through magnet coupling when the liquid level reaches at the set point. This reed switch contact may be utilized for the pump control, valve control, alarm message etc. for safety and automatic operation of various processes.

FEATURES

□ Compact and durable design

□ Perfect isolation between process and electric compartment for safety by magnet coupling

□ 316SS liquid wetting parts for high anti-corrosive capability

□ High pressure rating

□ Easy handling and installation
