Miniature Float Sensor

Main feature

Compact and low cost. Offers a wide range of designs.

Compact and low cost solution. Various designs available as standard to suit vertically any liquid applications.

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

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

High reliability and safety

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

Suitable for virtually any applications

A wide selection of components and attachments allow flexible adoption to any environments with short delivery time.

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

OL can be used to measure fuel, lubricant oil and other liquids except on the decks, bridges and cargo tanks. (Except side mounted OLH)

Principle of Operation

he sensor uses a magnet and a reed switch to detect liquid presence. The reed switch has its contacts encased in a glass tube with inert gas, and operates by an applied magnetic field.

The figure shows the float and the stem. The float integrates a magnet, and the stem a reed switch at the set point. The reed switch opens or closes as the float goes up or down on the stem.
