Level sensors for bulk solids

Sensor Family	Insertion Lengths	Technology	Signal	Points to Consider
LMC	10…40 mm	Impedance spectroscopy	• Switch • IO-Link	• Suppresses residue, splashing and foam • Reliable alternative to tuning forks • Media differentiation capability
KG, KI, KQ	Measuring range up to 40 mm	Capacitive	• Switch • IO-Link	• Senses through mounting well, sight glass, plastic tank or direct contact • Innovative bar graph display available • Low profile KQ housing mounts on flat surface
UGT, UIT	Measuring range up to 8 m	Ultrasonic	• Switch • IO-Link	• Accurate level detection regardless of medium • Actual distance available via IO-Link
O1D	Measuring range up to 9.8 m	Photoelectric	• Switch • IO-Link	• PMD time-of-flight • Colour / angle independent • Distance / level via IO-Link
KQ10	228 mm stackable	Capacitive	• Switch • IO-Link	• Mount outside non-metallic tank using brackets or adhesive • Units may be stacked to cover larger tanks • At-a-glance level indication via LED bar graph
