BE-R particular use sensor
Liquid level detection
- Reliable detection of liquids with a thru-beam type
- No malfunctions caused by crystallization or corrosion
- Non-contact detection of fluid media
- Tanks can be exchanged without the need for re-adjusting the sensor
- PNP and NPN output types available
