Water sensors

Banner Engineering World-Beam QS30H2O opposed mode water sensors provide a solution for efficiently detecting water-based liquids in clear, frosted, coloured or even partially opaque bottles or containers. QS30 water sensors use a specially designed 1450 nm sensing beam, which is inherently absorbed by water, to make the previously challenging clear bottle/clear water combination detection a high-contrast application, enabling reliable detection. In addition, QS30 water sensors have high excess gain to ‘burn through’ coloured glass, labelled or decorated bottles and translucent milk jugs to detect the liquid contents.

QS30 water sensors consist of an emitter and a choice of either a low-power receiver, suitable for detecting water in clear bottles, or a high-power receiver, designed to effectively receive the emitted beam through partially opaque containers. In addition, the 13 mm diameter beam can be shaped using one of the three apertures that come standard with each emitter/receiver pair. The aperture reduces excess gain and narrows the sensing beam, facilitating accurate detection of water in vials, test tubes or other small vessels and containers.

The QS30 water sensor is a suitable solution for demanding sensing applications, including: fill level inspection in bottling applications, test tube liquid detection and food packaging inspection and verification.
