TFLS2-01 | Compact tuning fork level switch. | Dwyer

The Model TFLS2 Compact Tuning Fork Level Switch is an ideal choice for levelcontrol of powders. The TFLS2 incorporates a piezoelectric crystal that vibrates the forkat its natural frequency. When the fork comes in contact with a material, the vibration isdampened and the switch changes state. As the fork becomes free of material, the switchchanges back to its normal state. Featured in the TFLS2 is user selectable fail-safeoperation of the contacts. The unit is not affected by vibration from conveying systems,motors, or the movement of material. Its compact size allows for mounting in places alarger tuning fork level switch may not fit, providing great versatility.

The Model TFLS2 is easy to use with adjustable calibration, and no mechanical movingparts means no routine maintenance. The TFLS2 is not affected by the dielectric constantof the sensed material, making it superior to a comparable capacitance level switch forapplications where the dielectric constant is low, more than one material is being used inthe single vessel, and when material moisture content can change. The level switch is alsogreat for applications when the bulk density is too low for a rotating paddle level switch,making it the ideal choice for low density bulk solids and liquids.
