Drip lub develops vertical mounting float switches that are specially designed for detecting liquid level in tanks. The float switches operate on the magnetic pickup principle. The float is manufactured of nylon. No, nc or both no and nc contacts [with contact rating of 1 amp at 220 v ac] can be supplied to the switch.. The manufacturer recommends that float switches can be used normally on 24 v dc supply. The fibre made square flange prevents electrical leakages. These float switches are available in heights of 50 mm and above. These switches are used in hydraulic powerpacks, remote tanks, lubrication units, underground and overhead tank automation. For uses in underground and overhead tanks, fully automatic level controllers can also be supplied.
