Key Specifications/Special Features:

  • Compact tuning fork level switch is an ideal for level control of powders
  • 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 fork becomes free of material, the switch changes back to its normal state
  • Featured in the TFLS2 is user selectable fail-safe operation of the contacts
  • Unit is not affected by vibration from conveying systems, motors, or the movement of material
  • Compact size allows for mounting in places a larger tuning fork level switch may not fit, providing great versatility
  • Easy to use with adjustable calibration, and no mechanical moving parts means no routine maintenance
  • TFLS2 is not affected by the dielectric constant of the sensed material, making it superior to a comparable capacitance level switch for applications where the dielectric constant is low, more than one material is being used in the single vessel, and when material moisture content can change
  • Level switch is also great 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
  • Service: dry powder compatible with wetted materials, can detect bulk materials submerged in liquid
  • Sensitivity:
    • Minimum bulk solid density: 4.4lbs/ft³ (70g/l)
    • Maximum particle size: 0.4-inch (10mm)
  • Wetted materials: 316L SS
  • Temperature limits:
    • Ambient: -40 to 140°F (-40 to 60°C)
    • Process: -40 to 266°F (-40 to 130°C)
  • Pressure limit: 600psi (40bar)
  • Power requirement: 20 to 250V AC, 50/60Hz
  • Power consumption: 10VA
  • Enclosure: aluminum, painted
  • Enclosure rating: IP65
  • Switch type: SPDT
  • Electrical rating: 5A at 250V AC
  • Electric connections: screw terminals
  • Conduit connection: 1/2-inch female NPT x 2
  • Process connections: 1-inch male
