Autonics BL13-TDT-P liquid level sensor uses a through-beam arrangement with a 950 nm infrared LED to detect liquid inside transparent tubing. The compact head mounts directly on small pipes and switches in as fast as 2 ms for reliable presence monitoring.
Features
- Through-beam liquid level detection for transparent pipe
- Applicable pipe OD 6 to 13 mm; 1 mm wall using FEP or equivalent
- Infrared LED 950 nm light source
- Fast response; max 2 ms
- Light ON or Dark ON selection by button
- PNP open collector output; 12 to 24 VDC supply
