TBL series - familiar to many by the name of dual-sinker liquid level relays - is a breakthrough product that is completely different from the conventional liquid level relays applying the mechanism of floats within liquid.
Conventional liquid level relays require 2 float switches for upper and lower limit controls of the liquid surface.
Kasuga's dual-sinker liquid level relay allows both upper and lower limit controls of the liquid surface using a single unit.
Operates regardless of the liquid resistivity. Not only in seawater and sewage water, the relay can also be used in liquids that do not conduct electricity (such as distilled water, oil, etc.).
Control range can be set and changed by varying the length of the handling rope.
Allows remote installation of control devices and alarm devices as the relay is unaffected by external induction or static electricity between electric wires.
Protection Code IP33 (rainproof type)
TBL 13FC (for oil) is not explosion-proof. Observe laws and regulations for use.
