When the liquid comes into contact with the sensor, it completes an electrical circuit, allowing the probe to determine the level accurately. Conductive level probes are commonly used in applications where the material being measured is conductive and non-hazardous.

Optical level

Optical level probes are used to measure the level of liquids in applications where other types of probes may not be suitable, such as those with aggressive or viscous fluids. These probes use light to detect the level of the material, typically by emitting infrared or visible light and measuring the reflection from the material's surface. Optical level probes are ideal for use in hazardous environments, as they do not come into direct contact with the material being measured. They are also suitable for applications where cleanliness and hygiene are essential, such as in food and pharmaceutical processing.
