Built for point level detection in liquids, this tuning-fork level switch signals when the fork is covered or uncovered. It provides a 5 A SPDT relay output and 20 to 250 V AC/DC operation. Its 316 SS 4" (101.6 mm) probe is rated to 600 psi (41.4 bar) and 130°C (266°F) and mounts via a 1" NPT male process connection. Best for high- and low-level alarms in tanks, vessels, and pipework.

The LTU-2000 Series tuning fork level switches are point level switches that detect high or low liquid levels. Based on the vibrating tuning fork principle, these units accurately detect contact with a liquid, triggering a switching output.
Depending on the liquid viscosity, the LTU-2000 is virtually immune to chemical or physical properties, and can be installed at any angle into a pipe or tank. Recalibration is not required between batches, and units may be cleaned in place. Models are available with PNP, NPN or relay.
