KOBOLD NSP polypropylene tethered float switches offer simple, economical liquid level monitoring.
They feature your choice of a tubular or ball float in polypropylene material with a 13′ TPK cable.
Filling levels may be controlled by installing at least two of the float level switches (one as a minimum, the other as a maximum limit switch). The two floats can be run to a latching relay (sold separately) for automatic liquid level control.
These plastic tethered float switches can be installed wherever magnetic liquid level switches are unsuitable due to the risk of the float jamming with dirt particles or coating.
Optional silicone and FEP clad cables are available for highly corrosive or solvent-based liquid applications.
