Magnetic float level switches

How to choose this product

A magnetic float level switch, or detector controls the level of liquid in a tank or other container.

Applications

These devices are used in a wide variety of situations requiring liquid storage and level control. Some require a model with a single float, while others are equipped with several floats for multi-point monitoring.

Technologies

The detector is mounted vertically in a tank. It consists of a rod holding one or more floats at different levels. A magnet within each float actuates a reed switch when its level corresponds to the contact point. The rod can be as long as three meters.

How to choose

Choice will depend primarily on the type of liquid concerned. Other factors include temperature, pressure and possible explosion risk. The number and position of detectors will determine the number of floats and the length of the rod.

Advantages

- Low cost
- Compact
- Effective
- Low maintenance
