FineTek SC Series Tuning Fork Level Switch | Industrial Point Level Sensor

FINETEK SC SERIES TUNING FORK LEVEL SWITCH  | INDUSTRIAL POINT LEVEL SENSOR

The FineTek Tuning Fork Level Switch (SC Series) is a rugged, industrial sensor used for point level detection in liquids, powders, and solid materials. It operates via piezoelectric crystals that vibrate the fork at its resonance frequency; when material covers the tines, the vibration is dampened, triggering a switch signal. A high-reliability vibrating level switch for liquid and solid detection that requires no calibration and operates independently of material properties like dielectric constant or humidity. High-precision FineTek SC Series vibrating level switch for liquids, powders, and solids. Maintenance-free point level detection with explosion-proof and high-temperature options. No calibration required. Shop the SC35 & SC10 series for reliable overflow prevention.

FINETEK SC SERIES TUNING FORK LEVEL SWITCH  | INDUSTRIAL POINT LEVEL SENSOR

The FINETEK SC SERIES TUNING FORK LEVEL SWITCH uses advanced piezoelectric technology to maintain a specific resonance frequency in the probe. It is engineered to withstand harsh industrial environments, offering various model types including standard, explosion-proof, and high-temperature versions. Its design eliminates common maintenance issues as there are no moving parts to jam or wear out, and its sensitivity can be adjusted to detect materials with densities as low as 0.01 g/cm³.

PRODUCT USES:

  • Liquid Level Control: High/low level alarms in tanks, pipes, and sumps for water, oils, and chemical solvents.
  • Solids & Powders: Level detection for cement, flour, feed, sand, and pharmaceutical powders.
  • Safety & Protection: Pump dry-run protection and overflow prevention in storage tanks.
  • Hazardous Environments: Level monitoring in petrochemical plants and coal mines using explosion-proof models.
