Conductive level switches

How to choose this product

A conductive level switch, or detector measures conductive liquid level in a vessel.

Applications

These devices measure the level of conductive liquids rapidly and reliably. They are particularly suited to protecting pumps from running in a dry state by turning them off. Some are specifically designed for use in the food industry.

Technologies

When fill level rises, the conductive liquid completes a circuit between the device and the vessel wall. The probe contains an electronic component which detects the current and activates a switch.

How to choose

Choice will depend on the fill material, the height of the vessel and the operating environment, including temperature, pressure and risk of explosion.

Advantages

- Sturdy
- Low cost
- No moving parts
- Suitable for very viscous liquids

Disadvantages

- Limited to use with conductive liquids
