Reliable fill level detection through transparent containers
Fork light barriers for fluid detection are suitable for fill level detection of clear, coloured or cloudy liquids through transparent container walls. They use infrared light to detect all liquids with a water content of over 15%. Thin films are ignored. This provides solutions suitable for difficult tasks such as detecting aqueous liquids in fine, transparent tubes with a small diameter (≤ 6 mm).
The fork light barriers are available with NPN or PNP switch outputs which can be switched to NC or NO as required.
- Fork width: 30 mm and 80 mm
- Connector: M8, 3-pin
- Enclosure rating IP 67
Fork light barriers detect limit levels even in exacting applications such as in fine, transparent tubes.
