TFLS2-01

TFLS2-01 is a TFLS2 compact tuning fork level switch. It is ideal choice for level control for powders. The TFLS2 incorporates a piezoelectric crystal that vibrates the fork at its natural frequency. When the fork comes in contact with a material, the vibration is dampened and the switch changes state. As the material is removed from the fork, the switch changes back to its normal state. Featured in the TFLS2 is user selectable fail-safe operation 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 a larger tuning fork level switch may not fit, providing great versatility. It is easy to use with adjustable calibration, and no mechanical moving parts means no routine maintenance. The TFLS2 is not affected by the dielectric constant of the sensed material, making it superior to a comparable capacitance level switch for applications.
