Miniature Float Sensor OL


Compact and low cost. It offers a wide range of design.

Compact and low cost solution. There are various designs that can be used vertically for any liquid application.

Insensitive to process conditions such as pressure, temperature and specific gravity

Unlike other technologies, OL provides a reliable measurement without being affected by temperature, pressure, specific gravity, capacitance or conductivity.

High reliability and safety

Among the high precision switch switches, only those that meet our original standards are used to ensure stable operation over a long service life.

Suitable for almost any application

A large number of components and attachment options provide flexible adaptation to every center with short delivery times.

NK (Nippon Kaiji Kyokai) certified (07A008) class

OL can be used to measure fuel, lubrication and other liquids outside the deck, bridge and cargo tanks. (Excluding side mounted OLH)

Miniature Float Sensor OL

Principle of Operation

The sensor uses a magnet and a reed switch to detect fluid presence. The contacts of the reed switch are placed in an inert gas glass tube and work with an applied magnetic field.

The figure shows the buoy and the stalk. The float integrates a magnet and the body includes a switching switch at the set point. The reed switch opens or closes as the float goes up or down the body.
